Study Of1064nm Fiber Laser Frequency Doubling

With the development of pulsed fiber lasers, the pulsed fiber laser was applied widely including industrial, military affairs and everyday life. Green fiber laser had a very large application because of excellent optical properties.There were two parts in this paper:the first part was Master Oscillator Power Amplifier (MOPA) all fiber pulse laser. The seed was a low power laser,17.47W pulse was obtained by using Multiple-amplification amplify10.45mW signal, the center wavelength was1064nm. The second part was external-cavity single-pass frequency doubling. MOPA all fiber pulse laser was used as a pump source of the frequency doubling system,750mW green pulse laser was obtained by using a2*2*10mm KTP crystal and12.58W laser power.
