Single pulse laser apparatus

A single pulse laser apparatus including a resonator having a first mirror, a second mirror, a gain medium, a first electro-optic modulator (EOM) configured to perform Q-switching, a second EOM configured to perform single pulse switching, and an acousto-optic modulator (AOM) configured to perform mode-locking, the single pulse laser apparatus comprising:

• a photodiode configured to measure a laser beam oscillated in the resonator;
• a synchronizer configured to convert an electrical signal, which is generated by measuring the laser beam, into a transistor-transistor logic (TTL) signal;
• a delay unit configured to set a delay time for the TTL signal to synchronize the EOM and the AOM and output a trigger TTL signal according to the delay time;
• an AOM driver configured to input the trigger TTL signal to the AOM that performs mode-locking and drive the AOM;
• a first EOM driver configured to input the trigger TTL signal to the first EOM that performs Q-switching and drive the first EOM;
• and
• a second EOM driver configured to input the trigger TTL signal to the second EOM that performs single pulse switching and drive the second EOM,
• wherein:
• the AOM consecutively performs mode-locking;
• the first EOM preforms Q-switching by outputting energy stored due to cavity loss generated through a wavelength plate;
• and
• the second EOM preforms single pulse switching.
