T. Joo et al., TI-SAPPHIRE REGENERATIVE AMPLIFIER FOR ULTRASHORT HIGH-POWER MULTIKILOHERTZ PULSES WITHOUT AN EXTERNAL STRETCHER, Optics letters, 20(4), 1995, pp. 389-391
We report a simple and robust Ti:sapphire regenerative amplifier witho
ut prepulse stretching. Pulse stretching by positive group-velocity di
spersion and negative third-order dispersion are provided by highly di
spersive flint glass prisms inside the regenerative amplifier cavity.
Using a single-grating compressor, we obtain transform-limited 60-fs G
aussian pulses at up to a 5-kHz repetition rate with energy of 50 mu J
/pulse.
