Oscillator and Amplifier Characteristics of Lasers Based on Nd3+ Dissolved in Aprotic Solvents

Abstract

Three different Nd3+ aprotic solvent laser solutions: Nd3+:SeOCl2:SnCl4; Nd3+:POCl3:SnCl4; and Nd3+:POCl3:ZrCl4 are considered in terms of their laser characteristics as oscillators and amplifiers. It is shown that such solutions have a loss that varies between 0.5 and 1.0% per centimeter and that their material efficiencies are at least comparable to those of an L.G. 55 (Schott) glass. As oscillators, the different solutions are shown to be equivalent to each other; as an amplifier only the SeOCl2 system was studied and this has produced gains of 18 dB in the small signal case.

High Energy Pulsed Liquid Laser

“…This characteristic of liquid lasers has been observed before (14) and will not be discussed here. At lower input energies, however, the plots do become linear and a linear extrapolation to a threshold can be made.…”

Spectroscopy and chemistry of aprotic neodymium(3+) ion laser liquids

“…The para fluoro derivative shows a very small increase in the proton hyperfine constants. If we use the oH to aF ratio of 3.97 to 8.41 G observed14 for the nitrobenzene anion and its fluoro derivative, one expects a fluorine hyperfine constant in the p-FC6H,tCH2 radical of 13.1 G which agrees quite well with the observed value of 14.04 G. A comparison of this latter value to the 6.17 G in the benzyl radical indicates that an a fluorine atom in a planar radical should have a hyperfine constant of ~50 G. This value is somewhat lower than the 64 G observed15 for the CH2F radical which is, however, slightly nonplanar as indicated by the 13C hyperfine constant.…”
