Q-switched laser News
For Glass and Silicon Wafer Cutting, Shorter Pulse Widths Yield Superior Results
Dec 8, 2016 — In manufacturing of semiconductor microelectronics, displays, medical devices and many other industries, there is an increasing trend toward higher-precision processing. This means cutting, drilling and marking parts with smaller feature sizes and greater accuracy, superior edge quality and with a reduced effect on surrounding material. In the past, most precision laser-based processing applications relied on nanosecond pulse widths or ultraviolet output (or both). But traditional sources
Understanding Passively Q-Switched Solid-State Lasers
Nov 5, 2014 — The operation of Q-switched lasers can be quantitatively understood – with huge benefits for laser design. In the September issue, we covered the operation and design of actively Q-switched lasers; this second part covers passively Q-switched...
Laser Car Ignition Dream Sparks Multiple Approaches
Sep 1, 2012 — Laser car ignition systems promise better fuel efficiency and lower pollution than conventional ones – as long as the technology continues to develop. As calls for improved energy efficiency and reduced auto emissions grow ever louder,...
Q-Switching a Fiber Laser with Another Laser
Apr 1, 2007 — When an application requires precise control of the timing and frequency of a Q-switched laser’s pulses, active Q-switching is the only way to go. However, for the many applications that don’t need such temporal control, passive Q-switching is often...
All-Fiber, Q-Switched Laser Generates 1.8 mW
Aug 1, 2003 — A team of scientists at the University of Science and Technology of China in Hefei has designed and demonstrated an all-fiber, Q-switched laser. High-power, single-frequency oscillation is obtained with a ring resonator, which eliminates the...
