HOU Lian-ping, CHEN Pei-feng, WANG Wei. Design of beam delivery system for RF CO<SUB>2</SUB> laser ceramic substrate scriber[J]. Editorial Office of Optics and Precision Engineering, 2004,(1): 37-42DOI:
The current requirements for laser ceramic substrate scriber systems are high light beam quality
fast scribing velocity
narrow scribing groove
small heat-affected zone
smooth cross-section
and independence of scribing quality from scribing direction. The light guide system designed can satisfy all the above-mentioned requirements
and it includes anamorphic lens
space filter
circular polarizer
Galileo defocusing telescope and focusing lens
and it has a scribing velocity of up to 10 m/min
a scribing width of less than 0.1 mm
and a scribing depth of more than 0.3 mm.
