Realtime FROG

High-resolution FROG with visual feedback on all important pulse characteristics: pulse duration, spectral width, chirp, pulse front tilt, phase modulation, dispersion.

Frequency-Resolved Optical Gating allows for a complete recovery of pulse intensity and phase of ultrashort pulses with complex shapes. It can retrieve the full time-dependant electric field and the equivalent optical spectrum with spectral phase. In other words, FROG allows you to know the duration of your laser pulses, but also how to deal with the spectral phase to achieve the shortest possible pulse duration.

Easy to Align
with the intuitive Femto Easy FROG software

Fast Single-Shot FROG

needs only one single pulse to measure the pulse properties

Multi-Shot FROG

measure pulses with energies as low as 5 pJ and covers a broad pulse duration range from 5 fs to 80 ps
