We have been using laser processing for many years to cut diamonds in the production of diamond styluses, as well as to drill sapphire, ruby and ceramics. Since customer requests for smaller diameter holes have increased in recent years, we introduced the UV laser (wavelength: 355nm) earlier than other manufactures in ...Read more

by K Mishchik2016Cited by 25 — The laser treatment is often continuous which is not necessary to perform glass cutting and may lead to over-exposure. In this paper we report on single pass glass and sapphire cutting using an USP laser (20W @200kHz or 8W@2MHz) using dash line laser treatment ...Read more

Oct 23, 2015 — Pulsed UV lasers enable machining with much finer detail, and their lack of excess heat adds another benefit — Each pulse removes a small amount of material but the high repetition rate turns it into a fast process. Nanosecond Nd:YAG lasers can micromachine sapphire substrates of any shape and a wide ...Read more
