Press Release Summary:

August 2, 2013 - Suited for dicing, scribing, and marking applications, Helios series delivers average and peak power that accelerate throughput in industries such as PV and electronics. These 1,064 nm, diode-pumped solid-state (DPSS), Q switched lasers, with pulse repetition frequency of 50 kHz and pulse width of <600 ps, are based on master-oscillator power-amplifier (MOPA) architecture. Oscillator ensures TEM00 circular beam with M2<1.2, and integrated amplifier stage allows modular power scaling.

Versatile Helios Lasers Provide Sub-Nanosecond Pulses for Superior Micromachining Results

Press release date: July 25, 2013

Santa Clara, Calif. – The new Helios series of sub-nanosecond solid-state lasers from Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) deliver superior results in dicing, scribing and marking applications.  With a pulse repetition frequency of 50 kHz and a pulsewidth of <600 ps,="" helios’="" unique="" combination="" of="" high="" average="" power="" and="" high="" peak="" power="" enables="" faster="" throughput="" in="" industries="" such="" as="" electronics="" and="" photovoltaics="" (solar).specific="" applications="" include="" scribing="" of="" both="" thin-film="" and="" c-si="" solar="" cells="" (e.g.="" selective="" opening="" of="" anti-reflection="" or="" passivation="" layers),="" dicing="" of="" silicon="" wafers,="" and="" precision="" marking="" of="" a="" wide="" range="" of="" products. ="" helios="" is="" particularly="" well-suited="" to="" black="" marking="" of="" metals="" and="" marking="" of="" delicate="" materials="" which="" would="" suffer="" peripheral="" thermal="" damage="" with="" fiber="">

The Helios series comes to Coherent as a result of its acquisition of Innolight, and becomespart of Coherent’s growing family of short-pulse, diode-pumped solid-state (DPSS) lasers.  These Q switched lasers are based ona master-oscillator power-amplifier (MOPA) architecture.  This two-stage approach is ideal for servicing diverse micromachining applications, since it provides the best balance of cost and power considerations.  Specifically, the oscillator ensures a superior TEM00 circular beam with M2<1.2, and="" the="" integrated="" amplifier="" stage="" allows="" modular="" power="" scaling="" to="" the="" optimum="" power="" for="" specific="" applications. ="" helios="" lasers="" are="" available="" at="" 1064="" nm,="" with="" 532="" nm="" to="" be="" released="" soon. ="" currently="" there="" are="" several="" output="" powers="" available,="" with="" total="" power="" up="" to="" 5="" watts. ="" at="" a="" pulse="" repetition="" rate="" of="" 50="" khz,="" this="" translates="" into="" apulse="" energy="" of="" 100="">

Founded in 1966, Coherent, Inc. is a world leader in providing photonics based solutions to the commercial and scientific research markets, and is part of the Standard & Poor’s Small Cap 600 Index and the Russell 2000.  Please direct any questions regarding this press release to Oliver Haupt, PLM, at +49 511 760 727 23.  For more information about Coherent, including product and financial updates, visit our website at http://www.Coherent.com.
