760nm high power single mode DFB laser 20mW (TO5 package oxygen detection)
With optimized optical properties, the 760nm single-mode DFB is ideal for demanding sensing system applications. The innovative chip design has suppressed high-order longitudinal and transverse modes while providing linear polarization stability. The laser has high output power, narrow linewidth and good consistency and is currently favored by domestic scientific research customers. We currently have in stock wavelength 760nm DFB for TDLAS oxygen detection, 795nm VCSEL for Rb atomic clock experiments, and 852nm VCSEL for CS atomic cooling.
Product features:Ultra-high output power、 Narrow linewidth、 Internal TEC and thermistor 、 2 nm TEC tunability
Application area:TDLAS oxygen analysis detection、 Optical coherence experiment
