Injection seeded single-frequency pulsed Nd:YAG laser resonated by an intracavity phase modulator.
A reliable single frequency Q-switched Nd:YAG laser is developed by using a lithium niobate crystal as the intracavity phase modulator. Successful injection seeding is performed by adopting an electro-optic crystal in an effectively simplified cavity arrangement. The laser is capable of producing 4.8 mJ pulse-energy at 400 Hz repetition rate with nearly Fourier-transform-limited spectral linewidth. The pulse duration is approximately 25 ns, and the beam quality factor M2is less than 1.3.
