Optical microresonators are structures which confine light to a small region in the range of one wavelength. A practical design for a single-mode microresonator is formed by two silver mirrors enclosing a transparent dielectric medium with single quantum emitters. The radiation of a quantum emitter is coupled to cavity resonances which leads to an optical confinement of the broadband fluorescence...
Nd3+-doped Ba(Zr, Mg, Ta)O3 ceramic laser is reported. The broadband fluorescence profile can be tailored by the “disordered” perovskite structure and is suitable for ultrashort pulse lasers. Mode-locked laser operation was demonstrated for the first time.
Optical microcavities are structures which confine light to a small region in the range of one wavelength. The radiation of a quantum emitter is coupled to cavity resonances which leads to an optical confinement of the broadband fluorescence.

Single crystal of Cr4+-doped LiGaSiO4 was shown recently to be promising active medium of solid-state lasers tunable within 1.2-1.4 mum. This crystal demonstrates intensive broadband fluorescence with the lifetime 15 musec. The substantial evolution of the optical absorption spectrum after devitrification had been observed in the range of 600-800 mum. The formation of grains of chromium doped crystalline...
