By inversing the signal and idler in a two-stagenoncollinear optical parametric amplifier which is, respec-tively, pumped by the second harmonic and fundamentalwave of femtosecond Ti:sapphire laser at repetition rate of1 kHz, the carrier-envelope phase (CEP) passively stabilizedpulses with a tunable wavelength from 1.1 to 1.6 μm areobtained with maximum energy of95 μJat 1.3 μm underthepump energy ofS00 μJ. The CEP jitter of pulses is 108 mradmeasured by anf-2finterferometer. This work demonstratesa new way to efficiently generate tunable near-infraredfemtosecond laser pulses with self-stabilized CEP. 相似文献
