Description

Single Longitudinal Mode lasers

The unique feature of the LaserBoxx DPSS is a proprietary, Alignment-free Monolithic Resonator (AMR). The elements of resonator are assembled into a single ultra-low-loss optical subsystem, using a proprietary crystal bonding technique. A highly transparent compound, deposited on chemically activated end-faces of two crystals, creates a bond that is extremly robust over time, temperature variations, and insensitive to mechanical vibrations. Dielectic mirrors coated at the end-faces of the crystals complete the monolithic assembly with no moving parts.
