The use of a split laser beam in laser material processing applications: a short review
A split laser beam is the output of a beam splitter DOE – an optical component generating an array of beams, often used in various applications including industrial, medical and sensing. This article introduces some innovative applications for a split laser beam in industrial material processing applications
Confocal Microscopy Using Laser Beam Splitters: Diffractive Beam Splitter Use Case
Background: confocal microscopy Confocal microscopy is a method where illumination is limited to small, diffraction limited spots, resulting in improved resolution. In a classical, single
Optical diffusers: design, production and use
Background: What is an optical diffuser? Optical diffusers are optical components that spread the optical power of incoming light beams i.e., diffuse the optical energy
Introduction to vortex beam
Introduction Over 60 years ago, a scientific breakthrough was the catalyst for the discovery of the first laser. Since then, the use of laser devices
Vortex plate application case study – STED Microscopy
Introduction Stimulated emission depletion (STED) microscopy is a well-known technique for achieving super resolution in microscopy that enables resolving sub-micron details that are smaller than
Uses of Phase plates to improve quality and yield in high power laser processing
Background: what is a phase plate? A phase plate is a diffractive optical element that superimposes a certain pre-designed phase profile on an input laser
