Fiber Laser Pumping

Unmatched reliability

Our fiber-coupled diode lasers enable reliable, lower-cost, and robust fiber-laser design alternatives across all types of power levels. The highly-integrated and ultra-compact 140, 200, and 335 W ST Series fiber laser pumps, the highest-brightness diode lasers in the market, have brought the power of kW fiber lasers to a wide range of machine-tool customers.

In addition, Lumentum offers ST2-L Series, locked fiber-coupled diode laser modules, available in different wavelength ranges. ST2-L modules are using internal locking technique to keep the wavelength range narrow, making them ideal for pumping solid-state lasers.
