Single Mode vs Multimode Laser Diodes
Laser diodes are semiconductor devices that emit light when an electric current is passed through them. The two main types of laser diodes are single mode and multimode.
Anti-Reflective Coating
An anti-reflective coating, also known as an AR coating or non-reflective coating, is a thin layer of material applied to the surface of a lens or other optical element in order to reduce the amount of light that is reflected off of it.
Dye Lasers
A dye laser is a laser that uses an organic dye as its gain medium. The dye is usually dissolved in a solvent, such as ethanol, and is pumped by a laser beam to produce laser action. The wavelength of the laser light is determined by the properties of the dye, and can be tuned by changing the dye.
What is laser speckle?
Laser speckle is a phenomenon that occurs when laser light is scattered by a rough or irregular surface or by a medium with inhomogeneities, such as a turbid fluid.
What is Laser Linewidth?
Laser linewidth is a term that is used to describe the spectral width of a laser beam. It is a measure of the range of wavelengths that are emitted by the laser, and is typically expressed in units of nanometers (nm).
Industrial Lasers: The Future in Material Processing
Lasers have been used in industrial settings for decades, but their use has been largely limited to cutting and welding applications. However, recent advances in laser technology are beginning to open up new possibilities for using lasers in a wide range of material processing applications.
How Safe Is Laser Engraving?
While laser engraving can produce highly precise and intricate designs, it is important to consider the safety aspects of this process.
What is a Laser Etalon?
A laser etalon is a device that is used to accurately measure the frequency of a laser beam. It works by using the principle of interference, which occurs when two waves meet and either reinforce or cancel each other out.
Laser-induced Plasma Spectroscopy (LIPS): An Overview of its Applications and Advantages
This article provides an overview of Laser-induced Plasma Spectroscopy (LIPS), a powerful spectroscopic technique used to analyze the elemental composition of materials.
Introduction to Gradient-Index Optics
Gradient-index (GRIN) optics are a type of optical technology that uses lenses or optical fibers with a refractive index that varies in a continuous and gradual manner.
