Method For Laser Source Definition in ZEMAX - Holo Or

1. Introduction. Any laser beam can be described by three parameters: wavelength, amplitude (or intensity) spatial distribution, and phase (or wavefront) spatial distribution. The unique property of a single-mode laser beam is a Gaussian amplitude and zero phase difference in the waist position. Multi-mode laser beams have arbitrary amplitude ...

Laser Types and Classification - Oregon State University

Types of Lasers There are many types of lasers available for research, medical, industrial, and commercial uses. Lasers are often described by the kind of lasing medium they use - solid state, gas, excimer, dye, or semiconductor. Solid state lasers have lasing material distributed in a solid matrix, e.g., the ruby or neodymium-YAG (yttrium aluminum garnet) lasers. The neodymium-YAG laser emits ...

laser | Definition, Acronym, Principle, Applications, & Types

laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths.

Laser Sources | Edmund Optics

Laser Sources differ from traditional illumination sources because they produce coherent light. The illumination spectrum is often narrow band with line widths as narrow as tens of megahertz and divergence as low as fractions of milliradians. Lasers are either utilized in free space, steered with traditional optics, or the source is coupled ...

Scientific Definition of a Laser - ThoughtCo

Updated on January 09, 2018 A laser is a device which is built on the principles of quantum mechanics to create a beam of light where all of the photons are in a coherent state — usually with the same frequency and phase. (Most light sources emit incoherent light, where the phase varies randomly.)
