IPG Laser GmbH, a subsidiary of IPG Photonics Corp. of Oxford, Mass., said it is introducing new pulsed lasers targeted at marking and new materials processing applications in the manufacture of silicon wafers, plasma and LCD display screens, and other devices. Four new products are now available and two more will be released next year, IPG announced at LASER 2007.World of Photonics, being held this week at the Munich Trade Centre. IPG has also introduced new 30- and 50-W average power models, adding to the 5-, 10- and 20-W average power devices now available in its YLP series. Its YLP lasers are now available with pulse durations of 25, 50 and 200 nanoseconds, in addition to 100-nanosecond devices. Frequency ranges from 10 to 1000 kHz with various collimator choices. Peak powers of up to 30 kilowatts are available. "The new pulsed lasers, which are application driven, greatly expand the opportunities for IPG's many qualified OEMs and integrators, as well as end-users," said IPG Photonics CEO Valentin P. Gapontsev. "With the expanded pulsed laser line, IPG's fiber lasers provide an alternative to conventional lamp-pumped and diode-pumped crystal pulsed lasers in a range of applications requiring higher powers because of the proven cost, efficiency, beam quality and reliability of fiber lasers." IPG said the new lasers can also be used in high-speed percussion drilling with minimal thermal effects, high-speed cutting of medical stents, silicon wafer processing, and applications involving the removal of thin coatings and those required by the manufacturers of plasma and LCD display screens. The new YLP-C series provides performance similar to its YLP product line, but with higher electro-optical efficiency, a more compact design and sophisticated pulse-management functions. In the high-power pulsed product family (YLP-HP), IPG also added 300-, 400- and 500-W lasers with frequency ranges to 50 kHz to its 10 mJ, 100- and 200-W devices. Pulse durations of these lasers can be specified from 200 to 1000 nanoseconds. In the YLP-HP series, IPG offers three models with 40- and 50-mJ pulses at 10 kHz with pulse durations from 150 to 1000 nanoseconds, as well as 100 mJ per pulse with 1-kW average power. In addition, IPG introduced the YLP-PSM pulsed laser product family, IPG's high quality and low-cost mode-locked picosecond laser for industrial applications. The first model produces peak powers up to 30 kW at an average power of 10 W, a pulse frequency of 35 MHz and a pulse duration of 10 picoseconds. The company said it is also developing a 50-W average power version. IPG said it expects to release additional pulsed laser lines in late 2007-early 2008, including a 150-kW peak power laser, 1 to 20 nanosecond tunable laser (YLP-T series) for high-contrast marking, and another picosecond laser family (YLP-PST series) offering, for the first time, direct triggering of 50-picosecond pulses with peak power up to 250 kW. It is exhibiting its new lasers at Area B3, Booth 439 at LASER.2007.
