| Abstract: | Compensating for the group velocity mismatch in optical parametric interaction with tilted pumping pulse fronts, an efficient femtosecond collinear type Ⅰ phase matched β barium borate optical parametric generator and amplifier pumped by a tilted second harmonic pulses of the Ti sapphire regenerative amplifier is demonstrated. The signal and idler outputs are tunable from 470 nm to 2.7 μm having pulse widths in the range of 100 to 170 fs at 1 kHz repetition rate. A maximum output energy of 6.5 μJ/pulse and a total conversion efficiency of more than 15% are achieved. |
