The control and measurement of femtosecond laser radiation parameters with Fabry-Perot interferometer

The method for measurement of different femtosecond laser radiation parameters using Fabry-Perot interferometer is suggested. The self- mode locked Cr:forsterite laser was used in our experiments. The average wavelength of a laser radiation lambda₀, laser radiation spectrum width deltalambda and general offset f₀ of frequency comb were determined.
