Where to Buy Frequency-resolved Optical Gating Devices

The FROGscan is an instrument for the full characterization of ultrafast laser pulses. A single device can use a variety of spectrometers that can provide wide wavelength range, high spectral resolution and over 75 dB of dynamic range. Wavelengths from 450 nm to >4000 nm and pulse durations from 12 fs to 10's of picoseconds are within the reach of a single system. A zero-dispersion design allows pulses <5 fs to be measured. The FROGscan is the instrument that can measure the most complex pulses.

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.

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.
