Silicate Nd:glass laser rod, 5 mm dia. x 100 mm length, vintage

Description

Professional, silicate Nd:glass laser rod, 5 mm dia. x 100 mm length, flat - flat ends (picture #1). Refurbished from a longer new, rod, cut at 100 mm length and polished with less than 10 arcsec parallelism. Due to the cutting, the uncut end is slightly thicker than the refurbished end (pictures #2, #3). Perfect internal homogeneity, seet hrough (picture #4). Vintage, mid 70', never used. Type Nd:glass: GLS-1, made in Russian Federation. For this laser glass the neodymium oxide (Nd
