Catalog excerpts

Multi-mode Fiber-coupled Diode Lasers ► Graphic Arts / Printing ► Direct Diode Lasers ► Robust Compact Package Fiber Core Diameter IPG Photonics' PLD-70 Series fiber-coupled diode lasers provide up to 60 W of output power within 0.13 NA. PLD-70 diode options include 105 urn or 110 u.m fiber core diameter, and center wavelength at 915 dichroic options are also available at 975 nm. 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-70 diode lasers are preferred for fiber amplifier and laser pump- ing, material processing, and direct diode applications.
