High power cw co2 laser.

Of the high power cw co2 laser beam in a system with an adaptive mirror g. Azurlight systems fiber lasers amplifiers are intended for researchers physicists and manufacturers for applications including argon gas laser replacement atomic and molecular physics high brightness laser pumping high performance instrumentation interferometry and laser dopler velocimetry. The physics and engineering problems associated with obtaining a uniform electric discharge at the required high power. Compass 115m continuous wave green lasers from 5 mw to 20 mw.

The co 2 laser can be operated in either cw or pulse mode commonly. Carbon dioxide co 2 laser a gas laser in which the energy state transitions between vibrational and rotational states of co2 molecules give emission at long ir about 10 µm wavelengths. The beam width varies from 3mm for low power lasers up to 100mm for high powered lasers. Continuous wave cw laser a laser that emits radiation continuously rather than in short bursts as in a pulsed laser.

Laser photonics mid power cw fiber lasers cover an output power range from 100 to 500w and feature a wide range of operating wavelengths single mode and multi mode options low amplitude noise high stability and extremely long pump diode lifetime. Continuous wave cw power output can ranges from few watts to over 15 000 watts. Family of co and co 2 lasers with power from watts to kilowatts for processing materials ranging from paper to metal. Plasma vapour ejected from the keyhole during high power cw co2 laser welding was investigated.

Means of controlling stabilising and reducing the effects of plasma formation are described. Coherent offers the broadest portfolio of completely sealed low power co and co 2 laser products in the market. A review of the electron temperature and density in the plasma is presented and difficulties faced in analysing the spectroscopic results are considered. Verdi lasers powers up to 20 w at 532 nm.

In pulsed mode peak power output can be in the millions of watts. Ipg s high power cw fiber lasers cover output power range from 1 kw to over 100 kw and feature a wide range of operating wavelengths single mode and multi mode options high stability and extremely long pump diode lifetime. Sawczak institute of fluid flow machinery polish academy of sciences fiszera 14 pl 80 952 gdańsk poland abstract a mirror with a controllable focal length designed for the high power cw co2 industrial laser was integrated into. Genesis lasers continuous wave lasers available from 355 nm to 1154 nm with powers up to 10 w.

The lasers are available with a wide variety of fiber terminations collimation. The laser can maintain continuous and very high levels of power. Recent advances in laser technology have resulted in the development of multikilowatt lasers which have been engineered for industrial applications. This family of sealed lasers is available in a wide range of models with output powers ranging from 20w to 1000w.
