A high peak power, low jitter single frequency eyesafe laser-a concept design

A high peak power low jitter, single frequency eyesafe laser with precisely controllable firing time is presented by a new injection seeding configuration, in which the oscillator can output energy of near tens to more than 100 mJ, with a pulse width of tens of nanoseconds and single transversal mode. Comparing with current existing techniques, this design presents a new approach of using the cavity entrapped, amplified seeding signal, injection seeding method to precisely control the high peak energy launching time within a nanosecond jitter and achieve single frequency operation at the same time. The advantage of the realized regime is that in stable laser operation there is no need to adjust the slave cavity length to match the seeded light longitudinal mode.
