Q-Switched DPSS Laser suits solar thin-film scribing.
June 26, 2009 -
Intended for high speed, multi-beam scribing of P2 and P3 layers in thin film a-Si and CdTe photovoltaic structures, HIPPO 532-14 provides 14 W of 532 nm output at 100 kHz with short pulse width of less than 30 ns. Scribe speeds in excess of 12 m/s have been achieved, and peak power is rated up to 16 kW at 50 kHz. Power and pulse width characteristics help reduce undesired thermal effects such as heat affected zones, material recast, and micro-cracking of substrate.

Newport Introduces Q-Switched DPSS Lasers for Solar Thin-Film Scribing
Rugged HIPPO 532-14 ideal for high-speed, multi-beam P2 and P3 scribing
Mountain View, CA - June 16, 2009 - Newport Corporation's Spectra-Physics® Lasers Division announces the HIPPO 532-14, a new addition to its HIPPO(TM) family of Q-switched diode-pumped solid-state (DPSS) industrial lasers. The HIPPO 532-14 provides 14W of 532nm output at 100kHz with a short pulse width of <30ns. Used for solar thin film scribing applications, the new laser is ideal for high speed, multi-beam scribing of P2 and P3 layers in thin film a-Si and CdTe photovoltaic structures. Scribe speeds in excess of 12 m/s have been achieved on tandem-junction a-Si P2 layers with isolation lines ~65 microns wide and ~2.5 microns deep.
Unique features of the HIPPO 532-14 include its short pulse width (<30ns at 100 kHz) and high peak power (up to16kW at 50 kHz); both help reduce undesired thermal effects such as heat affected zones, material recast, and micro-cracking of the substrate. The exceptional pulse-to-pulse stability of the HIPPO 532-14 at higher pulse repetition rates (up to 200kHz) translates to excellent scribe consistency at high processing speeds on solar panels. The TEM00 beam profile and superior beam quality (M2<1.3) translates to a larger depth of field for the HIPPO 532-14, making it more forgiving of variations in glass substrate flatness and surface irregularities. With proprietary EternAlign(TM) permanent optics mounting technology and field replaceable key components such as diodes, fibers, and harmonic modules, the HIPPO 532-14 is rugged and has a low cost of operation.
"The exceptional features of the HIPPO 532-14 result in higher throughput, higher yields and lower cost of operation for photovoltaic scribing applications," notes Julien Klein, Product Marketing Manager for Newport Spectra-Physics Lasers Division. "Our large installed base of HIPPO lasers around the world, combined with our attention to design and testing for product reliability, and our global service and support staff makes the HIPPO 532-14 the ideal laser for high uptime photovoltaic manufacturing applications."
The new HIPPO 532-14 laser will premier at Laser World of Photonics, June 15 - 18, 2009 in Munich, Germany, at the Newport Spectra-Physics booth #101 in Hall C1. For more information on the HIPPO 532-14 laser, please visit www.newport.com/HIPPO.
