S760 nm Laser Diode

Description
This monolithic laser diode incorporates a distributed Bragg reflector (DBR) for stable frequency performance over its life time. It provides a diffraction limited, single lateral and longitudinal mode beam. Facets are passivated for high reliability. The 760 nm Laser Diode is designed specifically for O2 detection.
Feathure
Wavelength tunable across several lines of the O2 spectrum
around 760nm
Pulsed operation for spectral stability at short pulse lengths
High power for CW applications
High Slope Efficiency
Technology
DBR Single-Frequency Laser Chip
AlGaAs QW Active Layer
Facets passivated to withstand high power
without catastrophic optical damage (COD)
Epi designed for high reliability
