PH920DBR
Photodigm PH920DBR 920 nm DBR laser
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. Applications for the 920 nm DBR Laser Diode include spectroscopy, difference frequency generation, and low power DPSS replacement. It can be ordered to a specific wavelength target for frequency doubling to specific trapping wavelengths.
- 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
- Wavelength tunable across 2 nm
- Pulsed operation for spectral stability at short pulse lengths
