Studies on 5 TW/40 fs Table-Top Ti∶Sapphire Laser System
A table-top Ti∶sapphire laser system with two-stage amplifier was built based on TSA-25 regeneration amplifier. Pumped by 0.6 J and 1.6 J, 532 nm, 10 Hz of Nd∶YAG lasers, the output energy reached 500 mJ and a pulse with duration of less than 41 fs was generated by using a single grating compressor, the energy convevsion efficiency of the compressor was 63% and the peak power reached 7.6 TW. By the experiments on the different absorption of crystals for 532 nm, pump-to-IR efficiency with pump fluence and passes of amplification, the system was optimized with an extraction efficiency of power amplifier ~32%, compacted less than 10 m2.
