Abstract
Remote sensing requires efficient lasers that are tunable over a short wavelength range around a particular atmospheric absorption feature of interest. High efficiency usually implies lanthanide series lasers. Although lanthanide series lasers have sufficient tuning capability, they must operate at preselected atmospheric absorption features. Often, there is no commonly available laser that operates at the requisite wavelength. This type of problem can be addressed using compositional tuning to create a laser at a preselected wavelength where none existed before. Quantum mechanics is an invaluable tool to predict the effects of compositional tuning. Quantum mechanical predictions are confirmed with spectroscopic measurements. Laser performance data for a laser that operates at 0.9441 μm, a preselected water vapor absorption feature, are featured.
