The femtoSHAPE-HP system is ideal for direct post-amplification compression and shaping of mJ-level femtosecond pulses. High-quality transmission gratings, water-cooled liquid-crystal-on-silicon spatial light modulator (LCOS SLM) heads, large-aperture dielectric optics, and sealed packaging enable high power/energy handling. Diffractive shaping offers both phase and amplitude control. The femtoSHAPE-HP configurations are optimized for laser sources emitting at 800 nm and 1030 nm, with up to 100 nm bottom-to-bottom spectral range. Fourier-domain pulse shaping by a programmable LCOS SLM does not require synchronization with a laser source, working equally well for laser repetition rates from 100 Hz to 1 GHz.

The femtoSHAPE-HP system 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. In addtition to automated dispersion compensation, the software offers built-in functionality for time-domain pulse shaping.
The femtoSHAPE-HP system supersedes the popular MIIPS-HD 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.
** Estimated maximum beam diameter. The aperture is limited by 15.9 mm width of the LCOS SLM.Close

* Diffractive shaping enables phase-only, amplitude-only and phase-and-amplitude control via a single mask 2D LCOS SLM.
** Spectral resolution depends on the input beam quality. It is estimated using measurements for femtoSHAPE-HP-800-90 with a collimated 6.5 mm 1/e2 dia. input beam, M2<1.1.
*** Defined as a ratio of the output power in the first-order-diffracted beam (after spatial filtering) to the input laser power. The SLM is programmed to apply “zero” phase and 100% transmission mask across the entire passband. The reported value is typical, the actual throughput depends on the pulse shaper configuration.Close
