FROG - Multi Shot

The Multi-Shot FROG(MS FROG) series

MS-FROG stands for Multi-Shot Frequency Resolved Optical Gating. The MS-FROG is based on second harmonic 

generation, making it reliable and compact. It has been specially developed for laser sources with sub-nJ pulse energy.

 It allows the measurement of pulses from 4 fs to 80 ps. The high scan speed allows real-time operations for 

measurement and optimization. The MS-FROG-SP allows the measurement of both ultrashort and long pulses thanks 

to its resolution of 50 attoseconds in fine scan mode. Our MS-FROG integrates in-house built spectrometers specially 

developed for FROG measurements. They guarantee high spectral resolution and the best performances for the 

application of pulse characterization. Also they are fully configurable according to your laser specifications. On top of 

that, our proprietary algorithm allows to extract information from each recorded spectra instantaneously, leading to real 

time reconstruction of your pulses! Like every Femto Easy product, the MS-FROG is easy to install and use.

Accessories and Add-Ons

The following Accesories and Add-Ons are available on request.

Option

Description

Additional crystals

The   default MS-FROG configuration includes one crystal. To extend the wavelength   range of the device, additional plug&play crystals can be ordered and   swapped within the system in seconds

Additional MISS spectrometer

The   default MS-FROG configuration includes one imaging spectrometer MISS. To   extend the wavelength range of the device, additional plug&play MISS   spectrometers can be ordered and swapped within the system in seconds

Fiber input connector

Plug&play   collimation module with fiber connector. Can be mounted on the MS-FROG to   easily switch the input from free-space to fiber. No alignment required.

Low energy

Internal   module to increase the sensitivity of the MS-FROG when the laser power is too   weak

Low repetition rate

Synchronization   mode to be used when the laser repetition rate is low. Mandatory for 100 Hz   and lower, recommended from below 500 Hz

Phase matching

Default   MS-FROG configuration works for a given central wavelength. Phase matching   allows tuning the SHG crystal to measure different central wavelengths with   the best SNR
