When Positive Light Inc. agreed to build a glassamplified laser for the Japan Atomic Energy Research Institute, it combined rotators and isolators from Electro-Optics Technology Inc. in a laser system designed to produce two 20-J uncompressed beams. The rotators were employed with large-aperture polarizers to optically isolate the amplifier stages from each other and to eliminate optical feedback into the amplifier chain.

The beams are used to generate x-rays for such applications as stereoscopic microscopy, ultrafast imaging, high-beam-energy diagnostics and ultraprecision machining.

Steve Edstrom, Positive Light's custom laser product manager, described the laser as a chirped pulse amplification system that takes a 200-fs pulse from a continuous-wave mode-locked Ti:sapphire oscillator operating at 80 MHz and extends it spectrally to >1 ns in a grating stretcher. It amplifies the pulse, first in a Ti:sapphire regenerative amplifier and then in a chain of Nd:glass amplifiers
