Pump and cavity effects in a passively Q-switched Nd:YVO4 lasers
碩士 === 東海大學 === 物理學系 === 96 === In this thesis, we experimentally study pump and cavity effects in passive Q switching of diode-pumped a-cut and c-cut Nd:YVO4 lasers. The average output power, pulse width, and period were measured as functions of the pump spot size and resonator configuration. Our...

The average output power, pulse width, and period were measured as functions of the pump spot size and resonator configuration. Our investigation shows that larger pump spot size is favorable for good Q switching. Suppression and enhancement effects on passive Q switching were observed near the border of geometrically stable resonator figuration. We also find that c-cut Nd:YVO4 crystal is a more preferable gain medium than a-cut one for generating short pulse width, high peak power, and stable Q-switched pulses. Based on these studies, the generation of Q-switched pulses with pulse width as short as 26 ns and peak power up to 150 W were achieved by use of a c-cut Nd:YVO4 crystal under pump power of 890mW.
