Tunable Lasers in Ophthalmology
Ophthalmologica, 1975The present status of laser application in clinical ophthalmology is breifly reviewed. The potentials of tunable dye lasers as retinal photocoagulators are discussed. Selective irradiation of ocular tissues over the full visible spectrum and the simplicity and reliability of recently developed waveguide lasers are the most attractive features of these ...

Proceedings of LEOS'94, 2002
Trivalent ytterbium has been shown to have favorable properties over trivalent neodymium as a 1 /spl mu/m laser source when pumped at 940 or 968 nanometers. These properties include a broader absorption band, a longer fluorescence lifetime and smaller photon decrement between the pump beam and the Yb/sup 3+/ laser emission. An additional feature of the

Wavelength tunable laser operation has been obtained from the solid-state crystal alexandrite (BeAl 2 O 4 :Cr3+) over the continuous range from 701 to 818 nm. The tunable emission was observed at room temperature and above in a homogeneously broadened, vibronic, four-level mode of laser action. In this mode the laser gain cross section increases from 7

The concept of a tunable Cerenkov laser is introduced and expressions for the operating wavelength and stimulated emission rate are developed. Emphasis is on the development of criteria which must be met if tunable far-infrared device operation is to be achieved.

Physical Review A, 1994
The possibility of constructing tunable x-ray lasers of photon energy in the kilo-electron-volt range is discussed. It is shown on the basis of channeling observations that an \ensuremath{\sim}3.3% change of the photon energy of an x-ray-laser scheme proposed recently can be obtained with a 100-K change of the temperature.

Tunable infrared lasers have been used in research laboratories for ultrahigh resolution spectroscopy measurements of molecular gases. While these lasers offer the potential for greatly improving instrument (e.g., laser spectrometer) performance, implementation of the instrument function is complicated by the nature of the laser source.
