Product Overview:

Eblana Photonics EP1550-NLW-B laser diode, available in the 1547 - 1553nm range, features an ultra-narrow linewidth making it ideal for coherent comms and metrology applications. Eblana's Discrete-Mode (DM) technology enables excellent SMSR and tunability at a highly competitive price. These devices are offered at 1550nm for tunable diode laser absorption spectroscopy specific to CH4 detection. These devices are offered with an integrated TEC cooler. They also offer a monitor photodiode for constant power feedback mode of operation. They ship standard with a single mode fiber an FC/APC connector. Other connector styles are available on request.
