Abstract
A single-longitudinal-mode (SLM) double-pulse injection-seeded neodymium-doped yttrium aluminium garnet (Nd:YAG) laser was established utilizing an RbTiOPO 4 electro-optic crystal to modulate the optical path of the slave resonator for generating a resonance condition. The Q-switcher was fired twice during every pump period. This enabled the laser to emit a pair of SLM laser pulses with a time separation of 200    μ s . Each pulse had a pulse energy of 13 mJ at 50-Hz repetition rate, pulse duration of 20 ± 0.5    ns , and linewidth of 30 ± 0.3    MHz (within 2 min). The beam quality factor of M 2 was < 1.22 . A frequency jitter of 1.4 MHz was obtained within 2 min.
