Comparison and optimization of continuous passively mode-locked Nd, Y:SrF2 and Nd, Gd:SrF2 lasers for sub-picosecond pulse generation
In this work, we report on a comparison of continuously pumped laser system based on 0.5% Nd, 5% Y:SrF<sub>2</sub> or 0.5% Nd, 5% Gd:SrF<sub>2</sub> generating around the wavelength of 1.06 μm passively mode-locked by a SESAM designed for low pump power operation. For the dispersion compensated cavity with a GTI mirror, the pulse duration of 386 and 415 fs at the repetition rate of 125 MHz has been achieved for 0.5% Nd, 5% Gd:SrF<sub>2</sub> and 0.5% Nd, 5% Y:SrF<sub>2</sub>, respectively. The spectral width of generated radiation points to non-transform-limited pulse and the possibility of further pulse shortening for both cases.
