Abstract
Provided is a multiple laser pulse oscillation method using multiple Q-switching capable of reducing peak power of laser and increasing energy efficiency. A multiple laser pulse oscillation method using multiple Q-switching includes: forming one period of light energy; exciting electrons of a gain medium by the light energy; performing first Q-switching during one period of the light energy; oscillating a first laser pulse by the first Q-switching; performing second Q-switching during one period of the light energy; and oscillating a second laser pulse by the second Q-switching.

A multiple laser pulse oscillation method using multiple Q-switching, the method comprising:
- forming one period of light energy;
- exciting electrons of a gain medium by the light energy;
- performing first Q-switching during one period of the light energy;
- oscillating a first laser pulse from the excited electrons of the gain medium by the first Q-switching;
- performing second Q-switching during the one period of the light energy;
- and
- oscillating a second laser pulse from the excited electrons of the gain medium by the second Q-switching.
A multiple laser pulse oscillation apparatus comprising a mirror, a wavelength portion, a Q-switching portion, a polarization portion, a gain medium portion, an output coupler portion, a first control portion, and a second control portion, the apparatus performing:
- forming one period of light energy in the gain medium portion as the first control portion applies an electrical control signal;
- exciting electrons of the gain medium of the gain medium portion by the light energy;
- performing first Q-switching in the Q-switching portion as the second control portion applies an electrical control signal during one period of the light energy;
- oscillating a first laser pulse by the first Q-switching;
- performing second Q-switching in the Q-switching portion during the one period of the light energy;
