Laser Power Converters
Spectrolab offers a variety of laser power convertors (LPC) optimized for maximum conversion of monochromatic laser light. The most common devices are multijunction GaAs devices for NIR lasers. However, metamorphic InGaAs PV convertors for lasers ranging in output wavelength from 900-1600 nm are also available.
2V Dual junction GaAs LPC
- Optimized for 810 nm wavelength laser
- 1.5 mm diameter active area
- 50-55% conversion efficiency
6V Dual junction GaAs LPC
- Monolithic power consisting of two cells in series
- 3 mm diameter active
- 30-35% conversion efficiency
