Coherent’s PicoPulse™ pulse stretcher/compressor filters enable high peak power in femtosecond pulsed laser systems, with a distortion-free round output beam. Free space operation in PicoPulse filters allows larger input beams to be used with many orders of magnitude higher power than chirped Fiber Bragg Gratings (FBGs).
Coherent’s proprietary packaging is designed to minimize the spatial chirp commonly found in chirped volume holographic gratings (CVHGs). This robust, compact format is less complex than equivalent dispersive diffraction grating pairs, which require multiple components with precise alignment adjustment. The output is stable over a wide range of temperatures, with nearly diffraction-limited beam quality.
