Ultra Lightweight SiC Based Mirrors for High Energy Lasers
Agency / Branch:
DOD / MDA
SiC materials offer excellent characteristics for high energy lasers applications. However, both monolithic and RBSI materials suffer from brittleness. This proposal builds on the concept of ultra lightweight C-C (SiC) composite structure, which yieldvery high thermal conductivity and modulus. Subsequently, chemical vapor reaction (CVR) process will be employed to render optical quality SiC surface. In addition, BaF2/ ZnSe optical coating capability will be studied.It is anticipated that under 2Kg/m2 aerial density SiC based mirrors will be fabricated. In addition, surface rms of 2Ao is expected. Commercial applications include high energy lasers, at lidars and FTS instruments.
