A long wavelength infrared laser system is disclosed where radiation from laser sources such as frequency-doubled Nd:YAG or a Cr:LiSAF is used to resonantly pump a gain medium consisting of a holmium-doped fluoride crystal having a high active ion concentration. The laser pump source has a pulse duration that may be short enough to gain switch a particular transition or long enough to allow end-pumping with high energy densities without damage. The gain material has an absorption approximately resonant with the pump source wavelength, and the dopant concentration is selected to maximize absorption strength for a given excitation. The output radiation from the laser system consists of one or more wavelengths including, in particular 3. 9 nm but also other infrared wavelengths such as 1. 4 m, 2. 9 m and 3. 4 m. , several of which may be produced simultaneousely from the same laser material through the mechanism of cascade transitions.

A lasing apparatus includes a laser medium and a pump source. The laser medium includes one of a Holmium-doped fluoride crystal or a Holmium-doped fluorozirconate ZBLAN glass fiber. The pump source generates pulses that resonantly pump the laser medium such that the laser medium produces an output from the Ilevel to the Ilevel of Holmium. The pump source produces pulses having a duration that is at least as long as a storage time of the Ilevel of the laser medium. The pump source pumps the laser medium with signals having a wavelength shorter than 1. 67 μm, with the laser medium producing an output having a wavelength of about 1. 67 μm.

Systems and methods for long range recognition and identification of objects and targets, and, more particularly, to long range imaging systems that include the use of mid-wave infrared laser illumination technology are provided. In particular, mid-wave infrared laser illuminated imaging systems and methods are disclosed for addressing, among other things, the problems associated with long range, day or night observations of targets through various obscurants (e. g. , fog, haze, rain, smoke). Such systems may be configured to operate in either a single, active illumination mode or in a dual, active/passive mode.

Optical lenses, systems, devices and methods for fabricating and manufacturing diffractive waveplate lenses that allow setting the focal length sign of an optical system by positioning the lens with its front or back surface with respect to an incoming circular polarized light beam. Applications for the lenses include optical systems comprising fibers, diode lasers, waveplates, polarizers, and variable lenses, particularly, in the form of a set of polymer films with re-attachable adhesive layers. And providing a flat mirror with concave or convex function due to diffractive waveplate lens coating.
