Abstract

Stable single frequency output around 943 nm was obtained from a quasi-continuous wave (qcw) diodepumped, Q-switched Nd:GSAG laser. The Q-switched Nd:GSAG laser was injection seeded with a single mode laser diode. Its frequency was stabilized by an active-control loop specially designed for a strong qcw pump. The spectral linewidth of the Nd:GASG laser was 41 MHz and the frequency stability was 10 MHz. The single-frequency-pulsed laser generated 32 mJ pulse energy at 10 Hz repetition rate. When the repetition rate was increased to 100 Hz, 5.6 mJ pulse energy was obtained by a thermal dynamic stable resonator. By tuning the seed laser, the wavelength of the pulsed Nd:GASG laser can be continuously varied from 942.1 to 943.1 nm.
