The Rofin-Baasel (Daventry, Northants, UK; www.rofin.co.uk) X-Lase is an ultrashort (10–30 micron) pulsed fiber laser. The high average power of up to 24 watts is achieved using an adjustable pulse frequency of between 1 to 4 MHz, making this laser an appropriate tool for micro-materials processing applications. The ultrashort laser pulses combined with high beam quality enables heat-sensitive materials and densely populated devices to be successfully processed. The technique significantly reduces the heat affected zone and shock affected zone on the component therefore eliminating the main sources of quality problems.
Industrial excimer laser
According to Coherent (Santa Clara, CA; www.Coherent.com), the new IndyStar delivers the longest tube lifetime of any compact industrial excimer laser, providing increased reliability and lower overall cost of ownership. The laser incorporates the company’s newest excimer tube design, the RoHS-Almeta, which delivers several billion pulses at 193 and 248 nm. Target applications are in precision manufacturing and inspection, where its high repetition rate and stablized, low-noise output are key requirements. Application examples include photomask inspection and inkjet nozzle drilling.
Laser engine chips
Intense Ltd. (Scotland, UK; www.intenseco.com) has announced the Power Core 808 family of very high brightness, single-emitter laser engine chips that are customizable to a wide variety of optics applications.

The Industrial Excimer Laser Base from J P Sercel Associates (Manchester, NH; www.jpsalaser.com) is an integrated, self-contained industrial laser base, gas handling, and utility system. For example, the laser can be shipped and set up without expensive plant gas and ventilation system installations. Also, a single ventilatd enclosure reduces the total exhaust volulme for improved heating and cooling costs; this further improves safety because all the gases from the supply and the laser are in the same location. Additionally, the laser can be transported away from a process location for repairs or maintenance wth little downtime for high duty cycle applications where time is money. The integrated module can accommodate the excimer laser, the gas handling system, power supply, vacuum pump, gas bottles, and more.
A member of the firestar v-series of lasers from Synrad (Mukilteo, WA; www.synrad.com), the firestar v30 is available as an OEM, air-cooled model. Based on waveguide design, the resonator technology produces a circular beam (typically M² <1.1) in both the near and far field. This near-perfect beam can be focused to the smallest achievable spot size, thereby creating the maximum possible power density on a work surface. This results in faster processing speeds and higher resolution for most applications.
