Abstract
Hybrid laser medium on the base of the Yb:YVO4 and Yb:YAG (and Yb:KYW) crystals with overlapping broadband gain contours in common cavity was experimentally analyzed. On the absorption and fluorescence data at liquid helium temperature, excited states lifetimes the energy of electronic levels of ytterbium in vanadate crystalline hosts were calculated and the lasing parameters of broadband transitions of doped ions were studied. It has been shown that, this way of forming of the stationary regime of ultrashort pulses generation with duration in accordance with combined gain bandwidth in the laser with hybrid active medium is perspective.
