Advancement of high-pulse energy and high-repetition rate 2-micron lasers

Abstract

The high energy pulsed laser at 2 microm with high repetition rate can offer extended range for DE weapons either as track illuminator laser (TIL) or direct use in DE applications such as further material investigation of the cracking propagation in materials. Design and developing laser systems with 0.1-1 J pulse energy and pulse duration in the range of tens to hundreds of nanoseconds has been a challenging task regardless of the approach used for achieving it especially in the 2-micron spectral region. Developing such systems and their performance will be greatly enhanced with the use of specifically designed volume Bragg gratings. Such gratings recorded in glass have the capability to operate at high peak and high-average powers. The team at CREOL has the flexibility and the means to manufacture them with a very precise custom defined efficiencies and the knowhow to chirp such gratings. The implementation of such gratings will elevate the performance of the 2-micron laser systems which is being developed at The University of Adelaide to significantly higher levels.
