Where to Buy Frequency-resolved Optical Gating Devices

Femto Easy offers two types of FROG devices for ultrashort pulse characterization:

• The Fast FROG is a single-shot FROG, requiring only a single pulse to measure the profile. It is easy to fully characterize pulses with durations from <5 fs to 10 ps and in a wide spectral range.
• The MS-FROG is a multi-shot FROG based on a scanned optical delay line. It can measure pulses with energies as low as 50 pJ. The same device can measure very short pulses and long pulses, from 5 fs to 80 ps.

These devices are very easy to install and use. They are also quite versatile as the built-in spectrometer can easily be changed for addressing different wavelength ranges, thanks to its plug & play design.

The orchestra™ FROG (Frequency-Resolved Optical Gating) combines SHG (second harmonic generation) and TG (transient grating) FROG in one device with total spectral range from 200 nm to 2 μm (up to 3.4 μm optional). It comes with user-friendly software for acquisition and phase retrieval.

Second Harmonic Generation FROG is the most popular spectrometer-less Frequency-Resolved Optical Gating method. Most of the pulseCheck autocorrelators by APE optionally integrate FROG and give access to complete pulse characterization. The addition of a special nonlinear crystal module and dedicated software opens the door to complete spectral and temporal pulse characterization. The FROG Option enables the pulseCheck to measure the spectral and temporal bandwidth and phase with just a few adjustments to the autocorrelator.

The FROG Option consists of FROG crystal(s), a plane FROG mirror and FROG measurement and retrieval software.
