SANTA CLARA, Calif., July 21, 2010 — The new Titan UV series from DPSS Lasers Inc., pulsed 355-nm solid-state laser systems with up to 5 W of average power, are typically used in applications such as solar cell processing, sapphire scribing, UV marking, indium tin oxide removal and micromachining.

Enabling fast marking and materials processing, the lasers feature TEM00 beam quality of M2 <1.3 for high resolution as well as stability of 5% over 8 h for repeatable processing results.

Pulse energies of up to 150 µJ make the lasers suitable for both industrial 24/7 “workhorse” operation and for delicate scientific experiments. Extensive lifetime and trouble-free operation are supported by a rigid sealed structure. For remote control and monitoring, they have a full RS-232 interface.

Built upon intracavity conversion technology, Q-switched and with field-programmable repetition rates from single-shot to 300 kHz, the lasers are suitable also for thick-/thin-film laser trimming, direct write/repair, microvia hole drilling, biological threat detection, polyamide cutting and drilling, and photobleaching.

Available in four models, the lasers provide peak powers from >150 to >6000 W, pulse lengths from <30 to <80 ns and repetition rates from 30 to 150 kHz. Typical beam diameter is 2 mm, pulse-to-pulse stability at constant temperature is <50 µrad, linear/horizontal polarization is >100:1, full angle beam divergence is <0.3 mrad, elipticity is <10%, and astigmatism is <0.3. Input voltage is 90 to 240 VAC, maximum power consumption is 900 W, and ambient operating temperature is from 10 to 35 °C.

GLOSSARY
photobleaching
A process that helps optical fibers recover from damage induced by radiation. When silica is irradiated, bonds break and attenuation increases. Light in the fiber assists in recombining the species released by the broken bonds, decreasing attenuation.
