Abstract
Provided is a single pulse laser apparatus. The apparatus including a resonator having a first mirror, a second mirror, a gain medium, and electro-optic modulators (EOMs) which perform each mode-locking and Q-switching, the apparatus includes a photodiode which measures laser light that oscillates from the resonator, a synchronizer which converts an electrical signal generated by measuring the laser light into a transistor-transistor logic (TTL) signal, a delay unit which sets a latency determined in order to synchronize a mode-locked pulse with a Q-switched pulse to the TTL signal, and outputs a trigger TTL signal according to the latency, and a Q-driver which inputs the trigger TTL signal to the EOM which performs Q-switching, and causes the EOM to operates.
