NEODYMIUM GLASS LASER HAVING AN OUTPUT AT 904 NM.

摘要

Laserable material doped with a quantity of neodymium ions in a low concentration (vis., 0.10-3 wt. percent) which results in the glass exhibiting a ratio of fluorescent intensity peaked at 920 nanometers over the fluorescent intensity peaked at approximately 1060 nanometers of at least 0.4 as measured by a Cary Model 14 spectrophotometer. The glasses enable the generation of laser light in a waveband with an optical center at about 920 nanometers at room temperature (approximately 20 DEG C) when positioned in a laser cavity which is resonant at 920 nanometers.
