Measurements of carrier-envelope phase changes of 100-Hz amplified laser pulses

Carrier–envelope-offset dynamics and stabilization of femtosecond pulses

“…Thermal changes in the amplifier and nonlinear optical effects in a subsequent hollow-fiber compressor may well add up. At this point, the only practical solution for phase-sensitive experiments with amplified pulses seems to be monitoring of the CEO phase [34][35][36] together with binning of the experimental results.…”

Measurement and Control of Carrier-Envelope Phase in Femtosecond Ti:sapphire Laser

“…Typically the amplification is operated at a low repetition rate with large pulse energy. To evaluate and further control the CEP slip of the amplified pulses, a single-shot measurement of the spectral interference (SI) is proposed [36,37]. Phase locking is achieved by modulating the pump power of the seed oscillator through the AOM which varies the transmitted power proportional to the phase error signal generated by the phase locking electronics.…”

Carrier-Envelope Phase Stablization of Grating Based High-Power Ultrafast Laser

“…CE-phase stable pulses from the oscillator were sent to the CPA system. An f-to-2f interferometer (Kakehata et al, 2002), spectrometer, and computer measured the spectral interferometry signal from which the CE phase was extracted. In the f-to-2f, the laser was focused into a sapphire plate for spectral broadening and then the infrared components were frequency doubled by a BBO crystal.…”

“…CE phase stabilization by controlling the grating separation 2.1 CE phase shift caused by grating shift in stretcher and compressor For the grating based stretcher and compressor, it has been shown that the pointing stability of the laser beam on the gratings may introduce CE phase noise to the amplified femtosecond pulses (Kakehata et al, 2002;Thomann et al, 2004). It was soon shown that the grating separation could also cause the CE phase drift of amplified laser pulses (Chang, 2006).…”
