Abstract
A diode end-pumped self Q-switched Cr4+ Nd3+: YAG laser was established wit
h 30-ns pulse width (FWHM) and 0.5-muJ pulse energy output. In normal pulse
pumping operation, the lasing threshold changed greatly from 122 mJ to 2.4
mJ as the pump pulse frequency varied from 1 Hz to 500 Hz due to pumping-i
nduced thermal effect. A pre-pumping method was proposed and the change of
the lasing threshold was reduced; programmable Q-pulse output with maximum
frequency of 16 kHz and high stability was achieved.
