The femtoSHAPE-HR is a state-of-the-art pulse shaping system offering high spectral resolution, high versatility and top-notch dispersion management capabilities. The instrument is customizable to accommodate ultrafast laser spectra ranging from tens of nanometers wide to octave spanning supercontinua. Unlike solutions based on acousto-optic devices, the Fourier-domain pulse shaping by a programmable liquid-crystal spatial light modulator does not require synchronization with a laser source, working equally well at repetition rates from 100 Hz to 1 GHz.

The femtoSHAPE-HR pulse shaper features a single- or dual-mask linear liquid-crystal spatial light modulator (LC SLM). The instrument comes complete with a compact spectrometer, nonlinear optical detection kit and a software package enabling push-button pulse compression to the Fourier-transform-limited duration using multiphoton intrapulse interference phase scan (MIIPS) technique. The software offers built-in functionality for time-domain pulse shaping and includes all necessary calibration routines to re-configure the instrument as the end user’s demands evolve.
The femtoSHAPE-HR system supersedes the legendary MIIPSBox640 product line.

*Depends on the center wavelength of the laser source. The estimates above assume 800 nm laser source. If the bottom-to-bottom laser bandwidth is narrower than the pulse shaper’s passband, the maximum power/energy limit should scaled down proportionally. Note that for low laser repetition rates (<8 kHz), the pulse energy threshold defines the limit on the input average power.

* Programmable spectral phase and transmission (if available) are encoded on every laser pulse, without synchronization with the laser source. This frequency-domain pulse shaping translates into corresponding changes of the time-domain profile.
** Depends on the pulse shaper configuration.
*** The SLM is set to apply “zero” phase and 100% transmission mask across the entire passband. The throughput is measured without a polarizer in front of the SLM aperture. The reported value is typical, the actual throughput depends on the pulse shaper configuration.
