Solid-state vibrational laser—KBr:CN^−
Optics Letters, 1984Laser oscillation at 2054 cm(-1) has been observed from a vibrational transition of the CN(-) molecule doped into KBr host crystals. At sufficiently large CN(-) concentrations, population inversion between the nu = 2 and nu= 1 vibrational levels is created by optical pumping of the 0 ?

Solar-pumped solid-state lasers
IEEE Journal of Quantum Electronics, 1987Results are presented for direct solar pumping of a Nd:YAG rod laser. Stable CW output of more than 60 W was obtained with a slope efficiency exceeding 2%. A compound parabolic concentrator, designed to increase the solar radiation coupled into the laser rod, was used in these experiments.

There are three types of lasers of which the active medium is formed by solid materials: 1. pn-junctions, directly excited by an electric current; 2. colour centre lasers, that are crystals with X-ray induced defects, pumped by other lasers 3.

Developments In Solid State Lasers
SPIE Proceedings, 1986The past 2–3 years has seen an accelerated pace of research and development in solid state lasers. Particularly active is the research into tunable solid state lasers and it is interesting to note how, in the laser’s 25th anniversary year, a great deal of attention is currently being paid to close relations of ruby, the first laser medium.

Nature, 1985
In 1985 SCHAWLOW and TOWNES [1] described the build-up of coherent light in an optical resonator, or laser. They noted that amplified coherent light would possess two desirable properties: precise, narrow wavelengths, and high brightness or focusability. The first laser, demonstrated by MAIMAN et al.
