We developed a visible-red to near-infrared wavelength tunable all-solid-state laser system utilizing an optical parametric generation process in a MgO doped PPLN crystal pumped at 532 nm by an amplified and frequency doubled picosecond passively Q-switched Nd:YVO microchip laser. A broad bandwidth, tuneable over 300 nm between 710 nm to 1015 nm, is accessible. Depending on the green pump light pulse energy, pulses with durations down to 69 ps as well as pulses with energies above 2 µJ were achieved with kHz repetition rates.
我们开发了一种可见红光到近红外波长可调谐全固态激光系统，该系统利用在掺氧化镁的周期极化铌酸锂（PPLN）晶体中的光学参量产生过程，由一个放大且倍频的皮秒被动调Q Nd:YVO微芯片激光器在532 nm波长下泵浦。该系统可实现710 nm至1015 nm之间超过300 nm的宽带宽调谐。根据绿色泵浦光脉冲能量，在千赫兹重复频率下，可实现持续时间低至69 ps的脉冲以及能量高于2 μJ的脉冲。
