PEARL™ FIBER LASER PUMP SERIES
The Pearl™ fiber laser pump series is optimized to meet the demanding requirements of high brightness pumping with minimal cladding light and imbedded feedback protection.
Pearl™ pump lasers use a proprietary fiber coupling technology to eliminate light in the cladding. nLIGHT’s proprietary single-emitter integration technology enables high power pumping without the need for fiber combiners, thus maximizing efficiency, cost-effectiveness and useful life.
- 1µm feedback protection
- Patented nXLTTM diode protection for extended life
- Low-current, fault-tolerant architecture
- Ultra-low cladding light
- Industry-leading wall-plug efficiency
- Plug and play compatibility with OptoTools™ DL system
- Electrically isolated housing
- Erbium/Ytterbium fiber lasers
- CW/pulsed fiber lasers

2 A non-condensing environment is required for storage and operation.
3 Thermal resistance is the diode junction temperature shift per incremental Watt of heat load.
4 The wavelength temperature coefficient is the wavelength shift per °C change at the diode junction.  |
