Abstract
A single-frequency injection-seeded Er:YAG ceramic laser with a pulse repetition frequency (PRF) running at 1645 nm is demonstrated. The Er:YAG ceramic laser is seeded with a Er:YAG non-planar ring oscillator (NPRO) laser. Pulse energy of 5.19 mJ, pulse width of 571 ns at a PRF of 1 kHz is obtained. The fluctuation of the average power is measured to be less than 1.1% in 30 min. The M2 factors are 1.23 and 1.39 in x and y directions, respectively.
