“…Several LD-pumped frequency-doubled lasers operating at kilohertz repetition rates have been reported in the literature. Green output pulse energies of 50 -70 mJ were generated at 2.5 kHz with two KTiOPO 4 (KTP) crystals by Pierre et al, 32) and Hirano et al 33) using two-stage amplifiers. To date, however, the green laser pulse energy has not attained levels above 0.1 J while operating in the kilohertz repetition range.…”

We describe a compact laser-diode-pumped, phase conjugate Nd:YAG master oscillator power amplifier system with a reduced number of components in the single slab amplifier geometry. This system is readily suited for pumping a Ti:sapphire amplifier, making it possible to construct a compact, high-repetition-rate, terawatt-peak-power chirped-pulse amplification system. An average infrared power of 362 W at a repetition rate of 1 kHz in a 29 ns pulse has been produced with an optical-to-optical efficiency of 14%. With a KTiOPO4 frequency-doubling crystal, an average green output power of 132 W at a repetition rate of 1 kHz has also been generated when pumped at an input incident power of 222 W, corresponding to a second-harmonic energy conversion efficiency of 60%. The average power at both infrared and green wavelengths represents a record performance for a single-amplifier system. We discuss in detail the design, performance and operation of the system including output power, optical efficiency, beam quality and stability.

“…1 Schematic of single-frequency oscillator and amplifier frequency laser achieved by using the resonance-detection technique in Q-Switching operation. Four zigzag Nd: YAG slabs were adopted in amplifier stage for minimizing thermal distortion and stress-induced birefringences which were used in many high-power solid-state laser designs [8][9][10]. The laser provides an output pulse energy of 800 mJ with pulse duration of 11 ns and near 3× diffraction-limited beam at a repetition of 100 Hz with optical-optical efficiency over 18%.…”

A laser-diode-pumped high efficiency, high pulse energy and single-frequency oscillator and amplifier for potential space environment applications have been developed and demonstrated using conductively-cooled heat removal. A diode-pumped injection seeded single-frequency oscillator was achieved by using the resonance-detection technique in Q-Switching operation, and Nd: YAG zigzag slabs based on "pump on bounce" are used in power amplifier stage for high-efficiency pulse energy extraction. Output pulse energy of 800 mJ with 11 ns pulse duration is obtained at a repetition rate of 100 Hz, with a near 3× diffraction-limit beam and an optical-to-optical efficiency of 18%. The experimental result shows that the laser has compact structure, high efficiency, reliability, conductive cooling and can be used for space environments.
