The MiniGreen ETR100 and ETR150 diode-pumped solid-state (DPSS) lasers have been launched by Snake Creek Lasers. Insensitive to ambient temperature changes without the use of thermoelectric cooling, the CW devices operate at 532 nm and produce <2% noise rms. Power stability over 2 h at constant ambient temperature is <±3%, and power stability over the wide temperature operating range is <±10%. Typical polarization ratio is 4:1, with more than 100:1 available with an optional external polarizer. Full angle divergence is 13 mrad, typical. Warm-up time is <1 min, dependent upon thermal management.
