Title: Laser drilling of superdeep micron holes in various materials with a programmable control of laser radiation parameters

Abstract

The possibilities of enhancing the efficiency of laser drilling of micron holes, increasing their depth, and eliminating their conic shape are studied by using a single-mode loop Nd:YAG laser with self-phase conjugation on the gain gratings and passive Q-switching by a scanned gradiently coloured F{sub 2}{sup -}:LiF crystal. Holes of diameters 15-150 {mu}m and depth up to 20 mm with the aspect ratio (ratio of the hole depth to its diameter) of 50-155 are drilled in various metals and alloys. It is shown that passive Q-switch scanning during drilling provides the increase in the depth and speed of the laser drilling of superdeep holes by a factor of 1.5-2. (laser technologies)
