PLD-80

Multi-mode Fiber-coupled Diode Lasers

IPG Photonics’ PLD-80 fiber-coupled diode lasers provide a minimum output power of 59 W within 0.13 NA. The PLD-80 diode laser includes 105 μm or 110 μm fiber core diameter and a center wavelength of 969 ±3 nm. Wavelength stabilization and dichroic options are also available. IPG’s best-in-class diode technology offers an ideal combination of power, reliability and form factor. We manufacture to rigorous telecom-grade standards in the world’s largest high power diode fab. Each wafer is individually qualified, which sets IPG apart from alternative industrial pump products using short-lived diode bars and bar-stack technologies. PLD-80 diode lasers are preferred for fiber amplifier and laser pumping, material processing, and direct diode applications.
