Saturation parameter and small-signal gain of a laser-diode-pumped Tm:YAG laser

摘要

We have studied the small-signal gain and the saturation parameter of a Tm:YAG laser in a longitudinal-mode, oscillation. By using the cavity loss method, a maximum small-signal gain of 4.3%/cm at a crystal temperature of 15℃ and a maximum saturation parameter of 13 kW/cm↑(2) at a crystal temperature of 25℃ were determined with an oscillation wavelength of 2013 urn. # 1998 Optical Society of America
