DPSS laser
Staff -- Test & Measurement World, 9/1/2005
Boasting twice the output of earlier models, the 85 YCA 020 diode-pumped solid-state (DPSS) laser delivers 20 mW of output power at 561 nm. The laser is linearly polarized and operates in a single-longitudinal mode with an M(superscript)2 factor of less than 1.2 and peak-to-peak noise of less than 3%. The output beam is nearly circular with an aspect ratio of less than 1.1:1. Typical drift over a 24-hour period is less than 5%. Melles Griot, Laser Group, www.mellesgriot.com.
