首页 Semiconductor Diodes DFB Laser Diode 1460-1530nm DFB laser diode Single mode narrow linewidth high-power DFB laser 760/795/852/1512/2004nm output power 20/40mW 1512nm high power single mode DFB laser 20mW (TO39 package NH3 detection)

    • 1512nm high power single mode DFB laser 20mW (TO39 package NH3 detection)

    With optimized optical properties, the 1512nm 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 1512nm DFB for TDLAS oxygen detection, 795nm VCSEL for Rb atomic clock experiments, and 852nm VCSEL for CS atomic cooling.

    产品特点Ultra-high output power、 Narrow linewidth、 Internal TEC and thermistor 、 2 nm TEC tunability
