Transient gain/loss in tunable solid-state vacuum ultraviolet laser media
Conference on Lasers and Electro-Optics Europe - Technical Digest (1994) 1-2
Abstract:
We have developed a model for the net induced gain as a function of pump fluence, based on a rate equation analysis of the populations of the 4f(n-1) 5d → 4f(n) level of the activator ions and of absorptive color centers. As an example, this has been applied to LiLuF4:Ce3+, in which we have also observed laser oscillation at 326.9 nm. The net gain is seen to rise rapidly with pump fluence before showing saturation and roll-off. This behavior can be explained by the creation of color centers that absorb strongly in the UV. We will present the results of similar measurements in the VUV on samples of LiYF4:Nd3+ and LaF3:Nd3+.Production of a high-density, long scale-length iron plasma using a capillary discharge
