Optic Laser technology involves the use of some devices that emit light rays through the process of optical amplification based on the stimulated emission of electromagnetic radiation. Laser is unique as it is different from ordinary light, as it has Spatial coherence which allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances, enabling applications such as laser pointers. They emit light over a narrow spectrum. Optic Laser technology have come to stay as it’s application is so broad. This technology has a wide range of technology like in DNA sequencing instruments, optical disc drives, photolithography, laser printers, barcode scanners, fiber-optic, semiconducting chip manufacturing, speed, and laser lighting displays for entertainment, military, defense, and law enforcement devices for marking targets and measuring range, free-space optical communication, laser surgery, and skin treatments, cutting and welding materials. At Alpine research optics we give the best range ofthin fused silica windowsand we are one of the biggest optic lens supplier.
Gas Laser
Gas lasers have been a very important Source of laser light but in recent times, many of them have been replaced with more compact low-cost laser diodes and partly with solid-state lasers. However, for some laser applications, certain types of gas lasers are hard to replace and therefore still widely used as the use of, carbon dioxide(CO2) lasers are still used in many industrial sectors.
Chemical Lasers
A chemical laser is a laser that obtains its energy from a chemical reaction like oxygen-iodine laser (COIL), all gas-phase iodine laser (AGIL), and the hydrogen fluoride (HF) and deuterium fluoride (DF) lasers, all operating in the mid-infrared region.
Dye Laser
The dye Laser is a liquid dye solution that serves as a lading agent.
Excimer Laser
Excimer laser or exciplex laser is an ultraviolet laser that is commonly used in the production of microelectronic devices, semiconductor-based integrated circuits or “chips”, eye surgery, and micromachining.
Solid-state lasers
Solid-state has a wide range of applications as they are widely used in metal processing, medical applications, like in eye surgery, RGB light sources in laser printers and projectors, environmental instrumentation measurements, and optical transmission systems.
Fiber Lasers
A fiber laser is a laser medium through its means of passing rays or beams is through an optical fiber. This Optical fiber is dropped with some earth elements like holmium, erbium, ytterbium, neodymium, dysprosium, praseodymium, and thulium. This fiber laser comes in various forms like the high index guiding fiber, the band gap-effect low index guiding fiber, hollow-core fiber, and solid core PBG fiber.
Photonic Crystal Lasers
Photonic crystal fibers are optical fibers that use a microstructured arrangement of material in a background material of different refractive indexes. The background material is often undoped silica and has a low index region.
Semiconductors Lasers
The semiconductor laser is a device that causes laser oscillation by flowing an electric current to the semiconductor. In the semiconductor laser, light is generated by flowing the forward current to a p-n junction, and this current flows in a forward bias pattern, the p-type layer is connected with the positive terminal, and the n-type layer is connected with the negative terminal, electrons enter from the n-type layer to the holes at the p-type layer. When this happens, both the p-type and the n-type meet at the junction, and an electron drops into a hole, and light is emitted.
