FROG-technique Covers 1800 – 2200 nm

FROG now covers the wavelength range of 1800 nm – 2200 nm and opens the door to precisely characterize pulsed laser systems emitting in the spectral region of 2 µm. Famous representatives of pulsed laser sources to cover this wavelength region are OPOs and classical OPAs. Beside this, Thulium- (Tm) and Holmium- (Ho) doped materials enable pulsed laser emission with comparatively high pulse energies. New candidates in this field are, for example, fiber-based pico-second sources such as master oscillator power...
