SpectraPhysics.jpgThe Spectra-Physics Lasers Div. of Newport Corp. has released the Pulseo 532-34, a Q-switched diode-pumped solid-state industrial laser that outputs >34 W at 532 nm with a pulse width of <30 ns at a repetition rate of 120 kHz. Applications include electronic package and printed circuit board singulation, ceramic scribing and edge isolation of c-Si wafers. Peak power is >13.5 kW, beam divergence is <0.3 mrad, asymmetry is >85%, and astigmatism is <0.2. The laser delivers a Gaussian TEM00 beam with M2 <1.3. Power stability over 8 h at constant temperature is ±2%, operating temperature is from 18 to 35 °C, and power consumption is 1.1 kW.

GLOSSARY
Gaussian beam
A beam of light whose electrical field amplitude distribution is Gaussian. When such a beam is circular in cross section, the amplitude is E(r) = E(0) exp [-(r/w)2], where r is the distance from beam center and w is the radius at which the amplitude is 1/e of its value on the axis; w is called the beamwidth.
