MIR scanning FROG
Specially developed to characterize the output of Fastlite high-flux MIR OPCPA sources, the Frozzer can measure pulses from 3 optical cycles to 5ps between 1 and 9µm.
The Frozzer is thus perfectly adaped to the temporal characterization of Yb, Er, or Tm-doped systems as well as signal, idler and DFG outputs of OPA and OPCPA systems.
With its optical head separated from the spectrometer (free-space or fiber connection), and including optics compatible with 1 to 9µm central wavelengths, the Frozzer can cover a wide spectral range, and thus characterize many different light sources, from Yb, Er, Tm-doped systems to signal, idler and DFG outputs of OPAs and OPCPAs.
Its ultra-long, high-resolution scanning range can accomodate pulses ranging from few-optical cycles to 5ps ensures that whatever the compression quality, it can be measured.
The optical head is designed with simplicity in mind, and can be re-aligned within minutes even by inexperienced users.
The third generation of femtosecond laser sources can deliver few-cycle pulses at central wavelengths where non-SHG-based techniques such as SRSI suffer from the lack of available high-resolution spectrometers. The Frozzer perfectly fills the gap with a versatile though simple design.
Extremely easy to operate, it is the ideal tool for MIR pulse characterization.
The ability of the Frozzer to measure chirped pulses or complex temporal shapes up to 5ps is very useful, weither you are building an OPCPA pumped by a few ps laser and you need to control the real pulse temporal profile during amplification, or you are doing experiments with pulses after an OPA and DFG where pulse compression is not straightforward.
