Tunable laser system for complex volume holographic optical elements recording
Abstract
The requested research instrumentation is an Optical Parametric Oscillator (OPO) emitting narrow band radiation from 192 to 2750 nm. This experimental setup provides an opportunity to produce excitation of different sensitizers in photosensitive holographic glasses and combine it with illumination by a highly coherent laser sources emitting in near IR region. This mechanism will enable recording complex holographic elements, e.g. narrow band spherical mirrors for transmitters and receivers. The proposed instrumentation will not only enhance the current ARO funded projects but will affect a number of research directions which utilize the use of PTR Bragg gratings for creation of lasers with narrow spectral width and narrow angular divergence. Research programs, which will benefit from the requested instrumentation, are in the areas of high power solid state lasers, transmitters and receivers for LIDARs, high power diode laser systems, spectral beam combining of high power fiber lasers along with stretching and compression of ultra-short laser pulses. Creation the new material which is PTR like glass for complex diffractive optical components in these systems looks very promising but the demonstration of the possibilities for the use of the new material cannot be performed with the current setup for spectral beam combining. The proposed instrumentation will allow creating glasses with new photosensitizers enable up-conversion of optical excitation and, therefore, developing complex holographic elements operating in near IR spectral region.
