The amplification of ps and fs pulses with peak powers of up to 4.5kW has been investigated in a single quantum well InGaAs tapered amplifier. The pulses with durations of 100fs or 2ps were generated by a modelocked titanium–sapphire laser. The amplified pulses indicate strong gain saturation and carrier generation due to photon absorption in the laser active region which causes a temporal broadening...
This paper reports the generation of fs light pulses by a passively mode-locked InGaAs master oscillator power amplifier (MOPA) system. The laser system generates chirped pulses with 6.2 ps duration, a center wavelength of 922 nm and 4 GHz repetition rate. Pulse compression by an external grating compressor reduces the pulse duration to 580 fs. The average power of the compressed pulses of 851 mW...
A master oscillator power amplifier (MOPA) generates chirped 3ps pulses at 920nm with a repetition rate of 4GHz. Without requiring CPA the pulses are compressed to 600fs with a peak power of up to 65W.
