Harnessing the Power of Q-Switched Lasers: from LIBS to Material Processing @thorlabs

Uploaded December 2024 | Updated September 2026, 2 hours ago

In this webinar, Ethan Baker, Photonics Engineer at Thorlabs Ultrafast Optoelectronics, will share insights on how Thorlabs has developed products based on customer feedback, discuss the laser-induced breakdown spectroscopy (LIBS) techniques and measurements, and review how compact Q-switched lasers generate intense, high-peak-power pulses and the underlying principles that enable their effectiveness in various material processing tasks.

$Holiday Laser Lights | Photonics in Everyday Life Have you ever wondered how holiday laser light displays work? These laser holiday displays project hundreds of laser beams, but how can so many lasers fit into such a small package? You might be surprised to know these laser displays only need a single laser. They use something called diffraction gratings to diffract the one beam into many. Diffraction is the property of waves that allows the bending around corners. It’s a result of the waves getting bent from obstacles and edges they encounter. This can be seen when placing small obstacles like a strand of hair in the beam of a laser. The diffracted waves at the obstruction’s edges interference, creating complicated patterns of light. When small line structures are placed side by side, they form a diffraction grating and can generate multiple beams even if the structures themselves are transparent like glass or plastic. By stacking multiple diffraction gratings in a row in different orientations, a dynamic pattern of beams is created.$
