Coherent announced significant upgrades to its FACTOR Series of fiber-coupled diode pumps, delivering increased output power, higher efficiency, and an expanded wavelength range. The product line now features enhanced power output at 880 nm, achieving 220W with a 200µm core diameter and 0.2 numerical aperture (NA). Additionally, a new high-power pump module operating at 793 nm has been introduced, offering 200W at the same core diameter. These advancements cater to both industrial and medical applications, including Thulium fiber laser pumping.
The upgraded FACTOR Series also introduces a wider locking range enabled by volume Bragg grating (VBG) stabilization, ensuring hop-free operation over a broad range of optical output powers. Coherent’s vertically integrated manufacturing and automated in-house micro-optics assembly processes ensure consistent performance and scalability for OEM laser manufacturers. Production ramp-up of the updated product line is scheduled for spring 2025.
