Abstract

A number of femtosecond laser systems have been created based on the amplification of chirped and supershort pulses and implemented in broadband ytterbium-doped laser gain media (Yb:KGW and Yb:YAG) with direct laser diode pumping. The use of various active element geometries in the form of thin plates and thin rods makes it possible to obtain pulses with an average radiation power of 10–100 W. The quality of the laser beam is close to that of a diffraction-limited beam. All of these parameters allow the use of laser systems developed for various technological and biomedical applications requiring high-precision laser exposure.
