Use of SiC in a High Power Spatial Filter for Stray Light Reduction

Thomson scattering measurement of the electron temperature and density profiles in high temperature plasmas is a well established experimental technique. The existence of high levels of laser-line radiation (“stray laser light”) in the detected scattered light signal can lead to difficulty in system calibration. Spatial filtering is a standard technique for improving the spatial profile…

High Energy Aperture Holder (MT-1, MT-1R)

Spatial filtering of a high energy laser beam is not a trivial problem when the energy density of the focused beam approaches the ablation threshold of the optical aperture material.Materials with a high ablation threshold have very low thermal conductivity; thus, depending upon the repetition rate of laser pulses, can become subject to melting proceeded…

Mercury Messenger Mission

NASA’s Mercury MESSENGER Mission was launched from Cape Canaveral on August 3, 2004. Lenox Laser, Inc. was commissioned by NASA to fabricate High Power Ceramic Apertures for spatial filtering which required laser drilling holes (a few microns in diameter) with great accuracy and precision. Ceramic is just one of many readily available materials Lenox Laser…
