LDM Diode Laser
Laserline LDM diode laser systems are primarily OEM lasers focused on compactness, reliability and ease-of-integration. The LDM is a 19” rack mounted laser unit, that is the same size of a desktop PC. It includes the diode stacks, a fiber-coupling unit, the power supply, cooling unit and micro-processor controller.
Technical features at a glance:
- Up to 6kW laser power from a 19” rack
- Beam quality comparable to a Nd:YAG solid state laser
- Easy integration into machine tools
- 5 year warranty on laser diodes
- Field replaceable service modules
- Ideal for welding, hardening, cladding and mobile laser applications.
The 19” rack mount technology offers a significant simplification of the laser integration in machines or systems. Its’ innovative small footprint allows the LDM to be easily fitted within the production area, for example inside a standard cabinet, within the processing enclosure, or even below the conveyor belt of a production line. The laser is perfect for OEM applications. Up to 6kW of output power is available from these compact units.
The LDM beam quality is comparable to that of a lamp-pumped solid-state laser, but with ten times the electrical efficiency and at a fraction of the size. This miniaturisation of the laser system leads to a significant reduction in the cost of investment and operation. LDM lasers therefore offer significant potential for not only replacing existing older technology lasers, but also for displacing conventional welding, repair or heat treatment processes.
To ensure a very high uptime of these laser systems, users are supported worldwide by Laserline teleservice, via the internet, around the clock. At the same time the latest generation LDM has been specifically designed for rapid maintenance and independent on-site servicing. The essential components of the system – diode laser head, cooling unit, power supply and control unit – are quickly and easily interchangeable as modules, even in the field.
LDM diode laser modules are complete with fiber-optic beam delivery, and appropriate process heads and application specific accessories are also offered.
- flashlamp , the SWA is fiber-coupled and the SWT is YAG or fiber depending on the wavelength.">Laser Welding
- metallurgical bond High surface quality, hardly any post-processing is necessary The laser beam creates a molten pool at the workpiece surface, to which is simultaneously added the coating material wire or powder , also molten by the laser. The exposure time is short and creates only a short delay, as the cooling is quick. The result is a layer that is connected with the basic material metallurgically. It is tougher than the coatings created by thermal spraying, and compared to hard chromium plating for example, it is harmless to health. The favoured lasers for cladding applications are Laserline diode lasers, both the LDF and LDM series. The characteristics and the top-hat beam profile of the diode laser create a particularly even melt pool, which produces fine-grained, pore-free and crack-free coatings. Post-processing is therefore reduced to a minimum. They can also be used to create very thin coatings, which until now could only be realised by hard chromium plating. These lasers are readily integrated with robotic systems for automated processing, and offer a full 3D capability. We offer them complete with fiber-optic beam delivery, processing optics and powder or wire delivery nozzles. Special nozzles are available for cladding the internal surfaces of tubes.">Laser Cladding
- Diode-Pumped Solid-State Lasers, are a well developed and reliable technology that offers strong levels of efficiency together with compact build designs. DPSS lasers have now replaced flash lamp laser technologies for most industrial and scientific applications. The use of a Diode Module to pump an Nd:YAG or Nd:YVO4 crystal, creates a light wavelength of 1064nm, although by changes within the resonator design a range of lower wavelengths can also be created, that can be useful for scientific laser applications and for industrial marking applications on troublesome plastic and glass materials. DPSS lasers are one of the most popular laser technologies due to efficiency, reliability and flexibility. Compact low maintenance systems with long-life diode modules Available from low power milliwatt systems up to high power kilowatt systems DPSS Lasers can be configured to deliver a wide variety of different wavelengths DPSS lasers continue to be one of the most popular and widely used laser technologies that can offer high power levels with good beam quality. They can also be configured as milliwatt lasers with very high beam qualities for scientific applications and for pointer diodes etc. DPSS lasers boast some useful technical advantages that are often overlooked for industrial applications in favour of fibre lasers - for example the ability to deliver very short nanosecond pulses, that allows high peak powers to be delivered at high repetition rates, with minimal thermal input. This can make DPSS lasers superior to standard fibre lasers for plastic marking and other heat sensitive applications. The capability to use DPSS lasers systems in continuous wave CW and pulsed modes, and at high repetition rates means that for industrial applications they can be used for a whole host of different processes, including laser cutting, welding, hardening, cladding and laser marking still one of their most popular uses . The larger beam size created in high power diode lasers along with the excellent power distribution means they are a more natural fit for some welding and cladding applications when compared with fibre laser technology. If you are interested in assessing different laser technologies Laser Lines can assist with trials to assess the suitability of specific laser technologies for a wide variety of applications.">DPSS
