Abstract

Renewed interest in solid-state lasers operating in the mid-infrared region of the spectrum has been driven by several specific needs both within the government agencies and the commercial sector of the market. Among the needs are: probes for remote sensing through the atmosphere, wind-shear detection, communications, and medical applications. Reasons to use mid-infrared lasers rather than more conventional near-infrared solid-state lasers are associated primarily with wavelength. Mid-infrared lasers can be used to match a particular absorption, emission, or transmission feature. For example, by using wavelengths longer than ~1.5 μm, the transmission of the vitreous humor of the eye is very low. As such, these wavelengths cannot be focused on the retina and are considered to be eyesafe. By using these lasers, either by themselves or coupled with nonlinear optical frequency conversion techniques, many needs for tunable lasers in the 1.5 to 5.5 μm region of the spectrum can be met. In this presentation, progress on solid-state lasers in the mid-infrared will be highlighted.
