Fine Hole Drilling Using the Phase Conjugate Laser
Using the Nd:YAG laser with the SBS-phase conjugate mirrow based on SF6 gas, the laser drilled hole on a 0.1 mm thik blade has been reported in this lecture.The primary experimental results show, that the fine hole with the exit diameter of 20 μm and the entrance diameter of 30 μm has been obtained due to the small laser beam divergence of this SBS-phase conjugate laser.
