Our hybrid lasers are set up by an association of proper solid-state and gas laser media in a single laser system, which can exploit advantages of both media. The solid-state laser can provide an easier control of pulse shape or a higher energy extraction to the amplified pulse, for example. The gaseous iodine laser could have a narrower gain linewidth and, particularly, a more homogenous beam profile, which is important for the ultra-high-power pulse generation. The department develops the hybrid systems with gaseous iodine amplifiers, which amplify pulses of either solid-state optical parametric oscillator or a optical fiber front-end at the wavelength of 1.3 μm. In the first case, we obtained 30-Joule energy at pulses with the duration of 2 ns. We collaborate closely with Research Center PALS, Institute of Radio Engineering and Electronics in Prague, and the Institute of Scientific Instruments in Brno.
