“…From the two-dimensional FROG trace, retrieved temporal and spectral evolution of the compressed pulse plotted, which reveals the spectral and temporal phase variations. We observe that the full-width half-maximum (FWHM) of retrieved temporal profile is ≈ 30 fs with relatively flat temporal phase variations, which changes from 1 rad peak to peak which is shorter than reported earlier [17,29] as shown in Fig. 5.…”

“…There is a reasonably good agreement of bandwidth and shape of retrieved and measured spectrum (Fig. 6, spectral profile) with considerably small FROG error G = 0.002835 [26][27][28][29][30][31], where G is a root mean square error between the experimental and retrieved FROG trace. The information retrieved from the pulse becomes reliable if FROG error is below than the noise level of the experimental trace [22][23][24].…”

“…The beam focusability was reduced because of higher thermal aberration which is due to characteristics of thermal lensing outside the pumped area in the crystal. Therefore, for proper amplification efficiency and good beam quality, one must compensate the thermal lensing [29,30]. The crystal cooling and thermal eigenmode in post-amplifier [29,17] are employed to compensate the thermal lensing.…”

We present 30 fs pulse duration home-made chirped pulse amplification Ti:sapphire laser system operating at a repetition rate of 1 kHz with 4.0 mJ pulse energy. The Ti:sapphire laser system with ∼ 819 nm center wavelength has a long-cavity oscillator, four pass grating stretcher, 8-pass pre-amplifier, 4-pass post-amplifier and a double pass grating compressor. The Peltier coolers and thermal eigenmode post-amplifier are introduced to compensate the thermal lensing of the crystal in the amplifiers and to enhance the beam focusability on the crystal. The Strehl ratio and M 2 value measured by employing the Shack-Hartman wavefront sensor HASO4 to observe the spatial profile and beam quality. The most sensitive single-shot second harmonic generation frequency-resolved optical gating diagnostic technique is employed to characterize intensity and phase of the output compressed laser pulses.

Abstract-This paper presents a 100-kHz femtosecond amplifier system delivering pulses with a duration of 35 fs and an energy of 7 J. The system does not include a stretcher, since the large amount of dispersion accumulated during the amplification process is sufficient to prevent self-focusing. Compensation in approximately all orders is achieved through a combination of a prism compressor, chirped mirrors, and a liquid-crystal modulator, allowing the amplified pulses to be shortened to nearly the bandwidth limit.

We report on the 825-nm center wavelength, 9.17 mJ pulse energy Ti:sapphire-based femtosecond laser system simulation carried out by Lab2 tools in LabVIEW (National Instruments, Inc.). The design investigation and characterization of stretched, amplified and compressed pulses made by intensity module and second harmonic generation (SHG) frequency-resolved optical gating (FROG) module in Lab2. The minimum pulse duration of ~37.80 fs at the output of the compressor end obtained by simulations. The variation of pulse energy, FWHM and central wavelength versus number of passes in the amplifier are computed. The lab2 tools help to design and characterize laser system before to set up on the optical table. The simulation results save time to calculate parameters which are essential in femtosecond laser system designing. The Lab2 simulation tools, along with financial constraints, it is easier, simple and efficient to obtain results in short time.
