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.
