Vv. Apollonov et al., SOLID-STATE LASER WITH SEMICONDUCTOR PUMP ING OF A DISK ACTIVE ELEMENT AND ASPHERICAL OPTICS, Kvantovaa elektronika, 21(6), 1994, pp. 577-580
A compact solid-state laser with aspherical optics and a thin-disk act
ive element is proposed. This laser is pumped from the base side by ra
diation from an array of semiconductor lasers. A resonator mirror, a d
iode laser array, an active element, and a cooling system are combined
in the same device. The use of a hybrid stable - unstable resonator i
n this laser makes it possible to weaken the diffraction scattering of
a focused laser beam and increase the power density at the focus. The
proposed configuration can be used in the construction of high-power
wide-aperture lasers of minimal weight and size.
