Abstract

ABSTACT Q-switching is a method to create high power- short pulses in laser material processing. Although fifty years passed after the development of this method, it is still used especially in the new developed fiber laser devices. High-energy pulses enable some micro-manufacturing applications which never been possible. For this reason, the importance of this technique can be emphasized for laser micro-machining applications. The aim of the present manuscript is to give beneficial information about Q-switch mechanism in laser micro-manufacturing applications and evaluate the rapid development of this technique from the viewpoint of industrial dimension. Thus historical development, theory, types and current usage fields of q-switching method were given in the paper

LAZERLE MİKRO-İMALATTA Q-ANAHTARLAMA

Öz

     Q-anahtarlama, lazer malzeme işleme cihazlarında yüksek güçlü çok kısa süreli darbeler üretmek için kullanılan, temelde resonatör kayıplarının ayarlanması prensibine dayalı bir yöntemdir. Yöntemin bulunmasının üzerinden 50 yıllık bir süre geçmiş olmasına rağmen, özellikle yeni geliştirilen fiber lazer cihazlarında etkin bir şekilde kullanımı söz konusudur. Q-anahtarlama sayesinde üretilen kısa süreli yüksek enerjili darbeler, daha önce gerçekleştirilmesi mümkün olmayan bazı mikro-imalat proseslerine olanak sağlamıştır. Bu bakımdan bu yöntemin malzeme işleme boyutunda incelenmesi önem taşımaktadır.
