The Excelsior One 1064-FC is a singlemode DPSS fiber-coupled 1064 nm IR laser with 100 mW of output power with single mode, polarization maintaining optical fiber. These fiber-coupled lasers offer outstanding power stability in harsh operating environments, and a polarization extinction ratio (PER) of less than -30 db over the specified operating temperature range. The fiber-coupled Excelsior One lasers are terminated with a FC/APC connector. The Excelsior One lasers are ideal for customers who rely on modularity in their instrument design. With the Excelsior One series, customers can choose among over 50 different versions in a single footprint and a single supply voltage. This enables maximum independence and the fewest design constraints.
