Introduction to Laser Crystal Optics


The laser is an amazing substance that is known for its high luminosity (billion times of that of the sun). It has incomparable collimation. The great power of laser has a tendency to melt even the hardest substance. For this reason, it has wide application in manufacturing, life as well as scientific research.

A laser device is equipment that generates the laser. On the basis of working substances, laser devices are

•    Gas laser
•    Solid laser
•    Liquid laser
•    Semi-conductor laser

Laser Optics is used in wide range of laser instrumentation or laser applications. It uses different substrates like laser crystal. Laser crystal optics provides superior performance at specific laser wavelength or over the range of wavelengths.

The Distinctiveness of Laser Crystal

Laser crystal has a unique composition and is doped with other ions like transition rare earth ions or transition metal ions. These ions in optics enable the crystal to amplify light as the laser wavelength on the supply of energy to the crystal. As compared to laser medium doped laser crystal optics have smaller absorption and emission bandwidth, higher thermal conductivity, and higher transition cross sections, which increase the probability of absorption or emission.

Laser Crystal comes in different shapes like cuboid, cylindrical, and thin disk. Its shape and doping density greatly influences the output of the laser beam.

How Does Laser Crystal Work?

A cavity emits a coherent light beam, it uses two main features of laser: a crystal medium and a system that give optical feedback. An external source of energy strikes the crystal of the laser that stimulates the emission of electromagnetic radiation. The collimating beams then reflect within an optical cavity and oscillate between opposing mirrors prior to emergence from the cavity in the desired direction.

Thus, these unique characters of laser crystal in optics find a wide range of application ranging from medical to automotive industries.

Everything You Want to know About Collimating Lens from Thorlabs or Elsewhere

Image
Collimating lenses are optical lenses that help in making the light entering into the spectrophotometer parallel. With a collimating lens from Thorlabs or elsewhere, one can control the field of view, spatial resolution of their setup, collection angles for sampling and illumination. Why are they important in the first place? One of the prime reasons for use of the collimating lens is high divergence result of a laser diode. It is made up of aspheric lenses, they do not pose spherical aberration. Collimating lenses are usually picked as and when a collimated beam requirement is between one and five millimetres. Where are they used and how are they used? Collimating lens is placed inside a collimator. An Optical collimator is utilized for calibration, testing and measurement. In one of the types of the collimator, patterns are projected into infinity. When a target is kept in the focal plane of a collimator, the uniform target seems extremely near. This phe...

Different Types of Lamps in UV-Vis Spectrophotometer

Image
An ultraviolet-visible spectrophotometer can measure the wavelength of light near UV and near Infrared range i.e. from 190 nm to 1100 nm. It is used in the quantitative determination of concentrations of the absorber in the solutions of transition metal ions and highly conjugated organic compounds. The UV/VIS spectrophotometer has a different specific sample cell (sample chamber), and cuvette (sample tube) and also have different types of light sources. The different light sources that are used in spectrophotometer are deuterium light source, halogen light source, deuterium-halogen light source , xenon light source, tungsten light source. Today the spectrophotometer comes with different light sources that change its wavelength automatically for optimized and interruption-free operation. The choice of a light source in the spectrophotometer depends on various factors. The desirable features for light sources are: •     Uniform light output over a specified w...

Learn How to Couple Optic Fiber with LED and Sensors

Image
Fiber optics or optical fiber refers to the medium and the technology associated with the transmission of information as the light pulses along a glass or plastic strand or fiber. The central core to the fiber is surrounded by a cladding and a protective coating. Ones the light is injected into the core it remains trapped into it until emerged from the opposite end; this is because the cladding has a slightly higher index of refraction than the core. The sensors, illuminators, and toys make use of inexpensive plastic fibers. The environment that requires electrical isolation or protection from the elements uses fiber coupled LED . Coupling of Optical Fibers to LEDs and Sensors Although many fiber couplers are available for various LEDs and light sensors one can connect silica and plastic fibers directly to LEDs and sensors. Here are different methods used to produce fiber coupled LED and sensors. Preparing the Fiber Ends To obtain the best results use the plast...
