SPI fiber laser

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.

Welding, cutting, marking and micromachining operations can be performed faster and more precisely with an SPI laser for better reliability, with less scrap and with improved productivity.

With a strong presence in North America and Europe, including research and development and manufacturing in the United Kingdom, SPI consolidates its growth in Asia-Pacific, the Middle East and Latin America.

Founded in 1999, SPI Lasers (or Southampton Photonics Inc) was a spin-out of the Optoelectronics Research Center (ORC) at the University of Southampton, quickly establishing itself as a world leader in the design and manufacture of fiber lasers. industrial.

Since 2008, SPI has been 100% owned by the TRUMPF Group, a German high-tech company specializing in the supply of machine tools and laser / electronic technology.

Beam quality options:

Type S - Single mode M2 <1.3
Generating a very fine dot size <20 microns with high power stability and great depth of field. Ideal for applications requiring small feature sizes.

Type Z - M2 <1.6
Delivers higher peak power and pulse energy with only a minor increase in spot size with good depth of field.

Type L - Low mode M2 1.6 - 2.0
General marking applications giving slightly larger spots and more suitable characteristics to make the marks visible to the naked eye.

Type H - High Mode M2 2.5 - 3.5
Offering high pulse energies, peak powers and even larger spots, ideal for wide lines, police-filled applications and large area coverage.

Type M - Multimode (M2 4.0 - 6.0) *
Coming soon Highest pulse energies and longer pulse durations ideal for welding and cleaning.
