| Abstract: | The high efficiency frequency doubling of fs pulses in BBO is demonstrated, which employed the frequency space chirp technology. One all solid state laser system is developed, from which four wavelength lasers from the far infrared to blue range, 1064, 532, 823 and 402nm can be output. The laser system is pumped by a LD pumped Nd:YVO4/KTP laser at 532nm, a Ti:sapphire laser , and the nonlinear second harmonic generation crystal BBO are used to generate different wavelength. Maximum average powers (repetition rate 100MHz) of 300mW at 823nm, 73mW at 402nm, are obtained when the pumping power is 2.5W. The frequency doubling efficiency of 24% is reached. The main characteristics of this system are presented. |
