Laser krypton lamps are typically used as consumables in YAG laser marking machine, which by operated in a continuous wave (CW) mode and discharge a constant current in the 10-50 Amp range between 100-250 Volts. The continuous light radiated induces constant gain in the Nd: YAG rod, generating a continuous laser beam. Krypton gas is almost always selected for CW applications because it has the advantage of specific line radiation which better matches the absorption peaks of Nd: YAG at the relatively low current densities employed in these lamp types. Unlike the flash lamp products, arc lamps are filled to relatively high pressures (5-10 atmospheres) to increase the conversion of electrical energy to radiant output. As a result, the system designer is often challenged to deliver the necessarily high breakdown voltages that are needed to ionize the gas. In addition to the constant current mode of operation, krypton arc lamps may also be operated in a quasi-continuous mode whereby the current is sinusoidal in nature and a modulated continuous mode whereby the current is switched back and forth between a relatively low and high current.
