Galvanometer Scanning Head Realizes Taper-free Laser Pointer Process
Fiber laser pointer laser produced by American company. High-speed taper-free drilling of transparent glass materials with chip sizes less than 20 μm. The result is a cost-effective solution that was previously thought impossible. The traditional laser drilling process usually results in the formation of a tapered hole. Therefore, a series of 5-axis beam steering systems are needed to dynamically adjust the incident angle of the laser beam to synchronize it with the drilling action, thereby minimizing the taper. However, these systems are expensive. It is also difficult to adjust and maintain.
In transparent material. The taper-free laser pointer process can be realized by the traditional galvanometer scanning head. in tradition. This process uses a green diode-pumped solid-state laser with a pulse duration of tens of nanoseconds, resulting in a chip size of more than 120 μm. For processes with chip sizes smaller than 20 μm, picosecond lasers are required; at the same time, taper-free processes require the same processes originally developed for green DPSS lasers. A laser was used with a repetition frequency of 1 MHz and a pulse duration of 50 picoseconds at M2 = 1.3 and a pulse energy of 50 μJ. Chips are often implemented at high speeds in glass and sapphire materials. Taper-free drilling with dimensions smaller than 20 μm.
