Laserline Laser diodes

The component-wide laser diode

Diode lasers generate laser light in a semiconductor wafer, which is supplied with energy by an electric current. These laser diodes called semiconductors are used in different configurations. There are solutions in which individual laser diodes are used (single emitters) as well as mounting several of these laser diodes on a so-called "diode bar".

To transform a laser diode into a diode laser system, several bars are stacked on top of each other and several stacks are optically combined. In this way, power can be scaled from a single laser diode to high performance systems. Laserline high power diode lasers are designed according to this principle and only bars are used.

The wavelengths used range from 900 nm to 1080 nm for a power of up to 45 kilowatts.

Laserline diode laser sources

An important parameter of lasers for industrial use is their efficiency (electrical efficiency). It describes the amount of energy supplied which is converted into light and emitted as a laser beam. While some lasers convert only a few percent of the supplied energy into laser light (CO2 laser, Yag laser, etc.), Laserline diode lasers achieve an efficiency of up to 50% (diode to part).

This is mainly due to the fact that the conversion of electric current in a laser diode reaches almost 70%. This is the main reason for the success of diode laser sources, in industrial production for more than 20 years.

LDM Laserline diode laser module from 1kw to 8 kW LDM Laserline diode laser module from 1kw to 8 kW The LDM diode laser series is available from 500 watts up to 8,000 watts always in a 19 inch rack. Laserline LDM diode lasers can be equipped with different types of optical fibers and optical accessories such as zooms, welding optics, homogenizing optics, etc.

Advantages of LDM Laserline series diode lasers

• Up to 8 kW in a 19 "rack
• 5 year warranty for laser diodes
• Beam quality comparable to Nd: YAG solid state lasers
• Ideal for welding, curing and other laser process embedded in a mobile station
• Ease of integration

The LDM Blue series from Laserline

High power blue laser: efficiency thanks to blue laser light

The LDM blue diode laser revolutionizes the processing of copper, gold and other highly reflective metals in multiple ways. The direct generation of laser power of up to 2 kW cw at the wavelength of 450 nm is unique and thus avoids complex and inefficient wavelength conversions.

The absorption, and therefore the efficiency of the process, is increased by a factor of up to 20 compared to lasers in the 1 micron wavelength range. The precisely controllable energy deposition of the diode laser allows the melting of copper without evaporation, leading to unmatched stability of the weld pool.

This opens up new application possibilities, such as heat conduction welding of thin copper foils, additive manufacturing, surface treatment with large homogenized spot.

Combinations of different metals can be made with copper as the first junction material, for example copper and aluminum or copper and steel, breaking the convention that copper should be the bottom junction material.

The Laserline LDM Blue diode laser is today the only laser in the world with such laser power in this wavelength range, ie 2000 watts at 450 nm.

Advantages of LDM Blue Laserline Series Diode Lasers

• Laser power (CW) in the kilowatt range at a wavelength of 450 nm
• Fast power control and power modulation
• Optimized absorption in highly reflective metals
• Industry proven system architecture
• Very stable process with low disturbance melt characteristics
• Welding stacked thin sheets and copper sheets
• Welding of dissimilar metals
• 19 inch rack for easy integration of the blue diode laser into existing systems

SPI fiber laser sources

SPI Lasers is one of the world's leading designers and manufacturers of fiber lasers, and one of the few to operate on a truly global basis. With over 350 employees serving customers in over 150 countries, SPI aspires to be the world's leading manufacturer of fiber lasers.
SPI offers a wide range of pulsed and CW lasers, as well as a number of after-sales services for individuals, small businesses, medium and large businesses and multinationals.

Les sources laser à Fibre

Industrial Laser Systems, est amenée à intégrer différents types de sources laser en fonction des demandes clients. Jusqu’en 2008 Industrial Laser Systems intégrait principalement des sources SPI qui sont aujourd’hui devenues des sources Trumpf, une société allemande de haute technologie spécialisée dans la fourniture de machines-outils et de technologie laser.

Parmi ces sources, nous proposons des lasers à fibres pulsés ou continus qui sont utilisés dans nos machines de soudage par laser mais aussi dans nos machines de découpe par laser.

Les lasers à fibre peuvent aussi être utilisés pour des applications de gravure laser, texturation ou micro usinage laser.
