Contrary to Slab Laser Technology, SSL (Super Sonic Laser) Technology generates a single mode, absolutely symmetrical laser beam without additional optics, producing an ideal tool for material processing.

This is the lightest High Power Laser in the world. It weights only 195 Lb/ 88 kg.The Laser Max 6000 is the only laser in the world in it’s power class that is small enough to be mounted directly on a Gantry or on the Robotic Arm of a Laser Cutting Machine for Heavy Duty Industrial Cutting or Welding, for Metal processing, Ship building, Aerospace or Automotive Industries.

This eliminates major problems with laser material processing, like:

•Contamination of the beam path in dirty industrial environments; special clean room environments required to prevent contamination in the working area.

•Complicated alignment process associated with flying optical components that require specific knowledge and training

•Inconsistency of the laser cut throughout the overall cutting area due to divergence of the laser beam over distance

By installing laser·max on a vertical Z-axis it is possible to convert the laser into a LASER TOOL for existing CNC machining centers. You can cost effectively Laser machine not only flat materials but large three dimensional components. (3D machining). This opens unique opportunities for Laser Technology in Industrial Cutting or Welding Industries for small and medium size companies and individuals that was previously available only for big businesses.

laser·max is a 10.6 um CO2 laser that can deliver up to 6 kW of high quality power (peak). It operates virtually as a sealed laser and can run with one Gas Bottle for nearly 2 years, or with one Gas Cartridge for 1/2 a year. Laser-max 6000 lasers produce a beam that processes material a rate equal to a 6000W laser, although it's average power is only 3000W. This is due to the combination of beam characteristics consisting of low M2, Zero ellipticity in x&y directions, and high quality single mode that allows smaller focus spot sizes, unique fast rising square wave pulsed characteristics and variable wave front profile, adaptable for the curvature of terminal optics.

The Laser-max 6000 can be pulsed at repetition rates of up to 20 kHz, ( we are working on a 100kHz model) with pulse durations between 10 and 1000 microseconds.

Adiabatic Expansion Cooling Gas dynamic Laser :

Hot gases expand through appropriately shaped nozzles from a high pressure, high temperature chamber into a low pressure chamber. This creates a highly non-equilibrium region were a strong population inversion takes place. Very high laser output power can be achieved. The diffuser is used to shock down the supersonic flow to subsonic speeds, then the gases are generally exhausted to the atmosphere.
Population inversions require that the lasing medium be forced as far as possible from equilibrium. In equilibrium, statistical thermodynamics tells us that the upper levels have an exponentially decreasing population as a function of increasing energy, which means that the lower quantum levels have a larger population than the upper levels, thus a photon is more likely to cause an absorption. In highly non-equilibrium situations, the populations are reversed and the upper level is overpopulated relative to the lower level, and a photon is more likely to induce a stimulated emission, hence laser action is possible.

Non-equilibrium turbulent flows are much more likely to occur in rapidly expanding stellar atmospheres where ideal equilibrium flows are rarely encountered. If adiabatic expansion alone can produce one of the most powerful lasers on earth, then this mechanism should also be one of the most prevalent astrophysical means of producing laser action.

MAJOR ADVANTAGES
•SSL Laser·Max is the only self Thermo-Balancing Laser Source in the world, resulting in cooling requirements handled by a Chiller 5 to 10 times smaller then conventional lasers of the same power.

•Due to the laser's efficiency coefficient, the power supply is smaller than that of a sealed laser.

•Laser-max series Technology can deliver up to 20 kW of power without a substantial increase in the size of the unit.

•SSL Laser·Max produces a perfectly round laser beam and requires no additional stand by or initiation energy source (i.e. UV lamp). It generates the highest possible quality laser beam as RAW and INSTANT POWER.

•SSL Laser·Max is the Smallest laser in the World for its power range. It can deliver up to 6 kW of CO2 Laser Power from a unit the size of a suitcase.

•SSL laser·max combines the advantages and power of a Gas Dynamic Laser with the size of a sealed laser.

The unique feature of this Laser is that tremendous Power can be delivered to the machining surface directly from the laser without any beam delivery components or flying optics.

•It is so small that it can be used in the role of a Mobile Laser Weapon for anti terrorist and Special Forces as well as a Portable, at-a-distance material cutting tool (steel and concrete) for Fire Departments and Rescue Operations.

•We believe that it is the most economical Laser energy generating solution available today.

Gas Dynamic Laser can produce highest possible TEM00 beam quality:

Gas Dynamic carbon dioxide lasers can deliver super power for R&D and military applications, but on the current stage do not have industrial applications
Flowing-gas CO2 lasers offer output powers from 500 W to multi kilowatt levels and, on a dollars-per-watt basis, are considerably less costly than their smaller radio-frequency (RF) excited relatives. These lasers have been the industrial workhorses for more than two decades and helped pioneer the use of lasers in the aerospace and automotive industries. However, their size, gas consumption, and ongoing maintenance requirements have always represented problems for many users.

Gas Flow carbon dioxide lasers are stationary by nature of the techniques they incorporate.

They are so big that they cannot be mounted directly on the equipment for optimum processing performance, and the power is too low for heavy duty industrial applications.

The overall efficiency of sealed lasers is lower then gas-flow lasers. For example, a 500 Watt sealed laser requires a 10 kW RF power supply and a 10 kW chiller dropping it’s efficiency ratio of Electrical power /optical power to 2.5 %.

There are limitations to conventional cooling of the gas media inside the laser cavity. With an increase in laser power and constant efficiency the sealed laser with, let us say 3000 Watts, will require 60,000 W RF power supply and almost the same size chiller. Power consumption for the end customer will be 120,000W. Very few companies will be able to afford this because it will rocket the cost of ownership to a totally unreasonable level.
It is clear for us that the next technological step in exploring the CO2 laser market for material processing will not happen with the current hardware based on the current laser technologies. The world is waiting for a new Laser System free from limitations.

Large scale 135 Kilowatt gas dynamic laser at Avco Everett Research Lab, Inc. was among the first of the high power lasers. Initially this research was classified by the U.S. government, even today information on these types of lasers is scarce. (Gerry, 1970)

Limitations of the Current Laser Technology:

Hundreds of thousands of lasers are used in material processing and related industries. There are areas where a Laser can compete, but cannot really take the place of conventional tools, such as water jets, plasma cutting, or hydrogen-oxygen welding due to a number of major limitations:

• Huge Size and Power consumption. Iindustrial lasers average 1.500 kG and 1.5 m3.

• Low electrical efficiency. You can use only 5% of the optical power from a power supply. The remaining 95% of access power goes through the heat exchanger or chiller, wasting another 100% of energy to remove this 95% access power. At the minimum, you double your power consumption and the overall Laser efficiency drops to the 2.5% level. This is very expensive Laser power.

This low efficiency leads to dramatic increase in power costs and expanding dimensions of power supplies and chillers.

It is clear for us that the next technological step in exploring the CO2 laser market for material processing will not happen with the current hardware based on the current laser technologies. The world is waiting for a new Laser System free from limitations.
