PEARL™ SOLID-STATE LASER PUMP SERIES

The Pearl solid-state laser pump series is designed to maximize fundamental mode extraction from end-pumped lasers. Disk and slab laser geometries benefit when long-term mode stability and beam quality are critical.

These pump lasers use a revolutionary fiber technology, PowerCore™, which delivers high-brightness, Gaussian or top-hat pump profiles to maximize overlap with the TEM₀₀ cavity mode for efficient brightness conversion to 1 µm. The industry-leading efficiency of these pump sources is enabling compactness, reliability and simplified cooling for the next generation of solid-state laser systems. Pearl’s imbedded nXLT™ single-emitter technology is resetting the benchmark for high-brightness semiconductor laser reliability.

1 Numerical aperture (NA) is the sine of the half-angle encircling 90% of the optical energy from the fiber.
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.
