“…Nevertheless, accurate data on the chirp and pulse duration can easily be extracted from the image by using scaling formulas and well-known relation between the autocorrelation width and the pulse duration. In our work [7] the values of the linear chirp have been extracted from these images plotted against grating separation, and for each image the autocorrelator function has been calculated as an integral of the image intensity over the "frequency" coordinate.…”

“…Our previous theoretical analysis has shown that the well-known nonlinear autocorrelator based on noncolinear second-harmonic generation (SHG) [13], in addition to pulse duration measurements, can provide measurements of the chirp of a fs pulse [2,4,13]. The SHG autocorrelation method has been verified experimentally with femtosecond pulses produced by the Ti:sapphire laser system based on the Colliding Pulse Amplification (CPA) scheme [7].…”

“…Ultrashort light pulse characterization, which in general includes determination of the temporal dependence of the instantaneous frequency (chirp) or, equivalently, spectral phase, is a difficult and complicated task [1][2][3][4][5][6][7][8][9][10][11][12][13]. Our previous theoretical analysis has shown that the well-known nonlinear autocorrelator based on noncolinear second-harmonic generation (SHG) [13], in addition to pulse duration measurements, can provide measurements of the chirp of a fs pulse [2,4,13].…”

A simple device, Frequency Tracer (FT), for simultaneous measurement of ultrashort light pulse duration and chirp is presented. FT operation is based on the two-dimensional image analysis (time versus frequency) of the non-colinear secondharmonic autocorrelator beam, and FT enables one to evaluate the temporal phase variation over the femtosecond pulse duration. The spectral information of a fs pulse in FT originates from the angular divergence of a second-harmonic signal beam, and there is no need to use the spectral apparatus. Femtosecond pulses duration and chirp measurements of the Ti:sapphire laser system multi-pass amplifier (MPA) during adjustment of the compressor pair of gratings were made.

Ultrafast or ultrashort pulsed lasers have become integral in numerous industrial applications due to their high precision, non-thermal interaction with materials, and ability to induce nonlinear absorption. These characteristics have expanded their use in microfabrication, semiconductor processing, automotive engineering, and biomedical fields. Temporal pulse shaping reduces laser pulse durations, often to shorter timescales than many physical and chemical processes, enabling greater control. Meanwhile, spatial shaping improves efficiency and precision in micro- and nanofabrication and biomedical applications. Advances in optical parametric amplifiers (OPAs) and chirped-pulse amplifiers (CPAs) have allowed for more refined temporal and spatial shaping, ensuring the preservation of high peak power while achieving ultrashort pulse durations. Additionally, spatial light modulators (SLMs) have facilitated sophisticated beam shaping, which, when combined with ultrafast lasers, supports applications like computer-generated holography and nanoscale fabrication. These developments underscore the growing utility and versatility of ultrafast lasers in both research and industrial contexts.
