Overview
IPG diode laser modules and rack units combine reliable single-emitter diodes with delivery fibers to provide integrated diode laser solutions for OEMs and end users. Offered as compact DLM OEM modules and end-user-ready DLR rack units, they provide collimator or bare-fiber output options and optional red guide lasers.

Key product types

• DLM (Diode Laser Modules): turnkey OEM modules with integrated driver electronics and cooling; available with collimator or bare-fiber termination; optional red guide laser.
• DLR (Diode Laser Rack Units): high-brightness, rack-mounted systems using diode-to-fiber combining of sealed single-emitters; end-user-ready for industrial applications.

Functional description
These diode lasers offer multiple output configurations and integrated features to simplify system integration. DLM modules are compact OEM components requiring only an external DC power source. DLR rack units are complete systems with stabilized wavelengths, narrow emission linewidths, sealed emitters and selectable air or water cooling. Units are compact, low-maintenance and energy efficient.

Applications

• Heat treatment and metal hardening
• Plastics welding
• Medical applications
• Optical laser pumping
