Solid State Laser

alt

The Kyma line of solid state lasers from Melles Griot (Carlsbad, CA) offers improved stability and performance by requiring fewer parts than diode pumped solid state (DPSS) lasers. Kyma technology supports wavelengths from the deep blue to the red. The first product in the Kyma line is the Kyma 488, which is available with 10 and 20 mW of output power at 488.0 nm, a critical wavelength for many biomedical and life science applications. The output beam is nearly circular (less than 1.1:1 aspect ratio), linearly polarized, and has an M2 factor of less than 1.2. The compact, conduction-cooled laser head incorporates thermoelectric cooling and automatic power control for stable, long-term operation and beam-pointing stability. Long-term power drift is less than 5 percent during a 24-hour period. The modular design consumes less than 15 W of wall power.
