Spectra-Physics: Industrial Nd:YAG Lasers

October 25, 2000

The Y70S is the newest family of OEM, industrial, diode-pumped Nd:YAG lasers from Spectra-Physics. The Y70S series is based on the same proven platform as previous Spectra-Physics Q-switched solid state lasers, but uses a longer cavity to produce a stretched pulsewidth and lower peak power. This makes the output particularly well optimized for high precision materials processing applications, such as resistor trimming, marking of semiconductor devices and wafers, diamond processing, and thin film scribing.

Y70S lasers deliver over 6.5 W at 1064 nm, at repetition rates of up to 100 kHz. Their output also features good transverse mode quality (M2<1.2), together with high spatial mode stability and excellent pulse-to-pulse stability. The result is a laser beam that can be easily focused to a small spot at the work surface for precision processing, and which provides highly consistent output for excellent process control and high yields.
