High Beam Quality

A laser amplifier of LD pumping Nd: glass with a high beam quality and stability, which amplifies nanosecond laser pulse, has been developed in this paper. Under 1Hz repetition frequency, when the flat top pulse of 3 ns width and 1 nJ energy is injected as the seed pulse, the average output energy of the laser amplifier is 115.3 mJ with a net gain of 109, the energy dispersion degree of the outputting laser is no more than 2%; the modulation degree near field is less than 1.23:1.

Abstract We demonstrate a compact picosecond master-oscillator power-amplifier (MOPA) system based on an Yb-doped polarization-maintaining double-clad tapered fiber (T-DCF) delivering pulses with over 1.26 MW peak power and average output power up to 200 W preserving near diffraction limited beam quality. The unique properties of an active tapered fiber enable to amplify the seed pulses directly with no need for applying of additional stretching technique. This simplified laser system can find the practical implementation in industrial micromachining.
