SELF-SEEDED SINGLE FREQUENCY SOLID-STATE LASER RING LASER, SINGLE FREQUENCY LASER PEENING METHOD, AND METHOD THEREOF

摘要

PPROBLEM TO BE SOLVED: To provide a pulse laser having a constant output energy with a constant pulse width and a single frequency. PSOLUTION: A half wave plate W1, a Faraday rotator F, etalons E1-E3, a gain medium R, and a Pockels cell PC are arranged in an annular resonator, and energy from a pump source is stored in the gain medium R until single-frequency relaxation oscillation pulses are formed in the resonator. The energy stored in the gain medium R is output as pulse laser beams by operating the Pockels cell PC at the detection of the relaxation oscillation pulses to reduce the intracavity loss thereof.
