Laser Diode Modules

By Raymax Lasers

Laser Systems have been used for metal welding for a number of years. They are capable of most weld geometry types and have many advantages over conventional welding techniques.

A more recent application for Laser Processing Lasers is Brazing and Soldering. The Automotive and Electronics sectors have embraced Laser Brazing and Soldering.

Lasers used for welding, brazing and soldering are present in many industries including Aviation, Automotive, General Fabrication, Consumer Goods, etc.

Some of the advantages of using Lasers for Welding, Brazing and Soldering include:

High Process Speeds
Excellent Joint Quality and Strength
Less Post Processing Required
High Surface Finishes
Excellent Process Control and Stability

The new, fiber-coupled OEM modules, LDM series, are suitable for price sensitive applications in plastic welding, soldering, pumping of fibre lasers or micro welding of metals. These extremely compact modules have evolved from Laserline's long experience in fiber-coupled diode lasers for material processing. They meet the highest expectations on high lifetime, long term reliability and ease of integration. A closed loop, maintenance-free water circuit assures optimum operating conditions of the diodes and thus a particularly long lifetime.
