LDM series


The space saving 19-inch conception makes the integration of the laser easier for plant constructors, thereby qualifying it as a standard industrial tool. Whether in a classical control cabinet, a processing station or underneath the conveyor belts of an interlinked production plant, the innovative design makes it possible to integrate LDM diode lasers’ space saving in the production areas. In a standard control cabinet, in a processing station or underneath the conveyor belts of an interlinked production plant, the laser requires no additional space and is thus perfectly suitable for OEM applications.

Multi-kilowatt power for 19" rack mount module

The system design of  the fiber-coupled OEM modules from of the LDM series is consequently focused on compactness, reliability and ease of integration. The LDM is a 19-inch rack mounted laser, the size of a PC. It includes the diode stacks, a fiber-coupling unit, the power supply, cooling as well as microelectronics , used to monitor and control the laser.


With the enhancement of LDM’s product family with the new 7 HE plug-in system, Laserline once again sets the standard for compact high-power diode lasers. Further development of the LDM technology makes development of new applications with laser powers of 6 kW possible. The beam quality of the fiber-coupled LDM diode laser is comparable to that of a lamp-pumped solid-state laser, only with ten times the higher socket output efficiency at a fraction of the size. A very simple handling due to the functional, standardized signal interface underlines this user-oriented product’s philosophy. 


The LDM module is based on the proven and continuously-developed Laserline diode technology. Today, it is used worldwide in many application areas and is characterized by high reliability and system stability. Therefore, Laserline’s diode lasers are offered with a five-year warranty on laser diodes. This period may be extended on request. 


User-friendliness is at the center of the LDM product’s philosophy. The miniaturization of the laser system leads to a clear reduction in investment and operation costs. So, LDM diode lasers have a great potential to be a substitute not only for existing laser applications but also for conventional methods, e.g. welding, repair welding or heat treatment.
