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 sources with energy per pulse of less than 1 nJ. It allows the measurement of pulses from 50 fs to 40 ps in the standard version. The scan speed is so high that it allows real-time operations for measurement and optimization. The MS-FROG-LP can perform scan at 130 ps/s, making it the fastest scanning FROG on the market. Also, the MS-FROG-SP allows the measurement of both ultra-short and long pulses thanks to its dual-mode (standard mode for pulse duration >=> 50 fs and fine-scan mode for pulse < 50 fs). On top of that, our recently developed algorithm allows to extract information from each recorded spectra instantaneously, leading to real time reconstruction of your pulses! Like every products, the MS-FROG is easy to install and use.

1 Effective spectral bandwidth to be defined within the accessible spectral range according to customer’s requirements. Additional spectrometers can be provided to address different spectral windows.
2 Low repetition rate available as an option.
3 Those values give an order of magnitude. The exact sensitivity depends on many parameters (pulse duration, beam profile, wavelength…)
GigaHertz / low energy (pJ) measurement sample
The measured laser was a SESAM modelocked VECSEL developed at ETH Zurich1, assembled, amplified and CEO stabilized at the University of Neuchatel2.
This was the very first measurement of a GHz rep. rate Laser with a single-shot device.
