Gas Lasers. Solid-State Lasers. Fiber Lasers. Liquid Lasers (Dye Lasers) Semiconductor Lasers (Laser Diodes) Additionally, these five types of lasers can be divided into subcategories based on their mode of operation: continuous-wave lasers and pulsed lasers. Furthermore, there are also multiple types of pulsed lasers.
A solar-pumped laser (or solar-powered laser) is a laser that shares the same optical properties as conventional lasers such as emitting a beam consisting of coherent electromagnetic radiation which can reach high power, but which uses solar radiation for pumping the lasing medium. This type of laser is unique from other types in that it does ...
The pump energy is absorbed by the laser medium, exciting some of its particles into high-energy state where these can interact with light both by absorbing photons or by emitting photons. Under certain conditions, as mentioned in earlier sections, the amount of stimulated emission due to light that passes exceeds the amount of absorption ...
A variety of different pumping mechanisms are used to achieve population inversions and these are typically dictated by the gain medium. Specific lasers and their associated media are discussed in Types of Lasers. In all cases, the goal is to achieve pumping rates, i.e., atoms per unit time per unit volume being raised to a metastable level ...
Electrical pumping can be via a DC current (as in laser diodes), an electrical discharge (noble gas lasers and excimer lasers), or a radio-frequency discharge (some CO 2 lasers). In a conventional (incoherent) light source like a lightbulb, an LED, or a star, each atom excited by input pump energy randomly emits a single photon according to a ...
Depending on the type of laser diode, different kinds of pump optics are used. It is also possible to use fiber-coupled diode lasers, which make it possible to separate the actual laser head from another package containing the pump diodes, so that the laser head can become very compact.

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 ...
The pumping light source can be any of several different lasers, including a nitrogen laser (3371 Å), a frequency-doubled Nd:YAG laser (5320 Å), or an XeCl excimer laser (3080 Å). The only requirements are that the pumping laser must be of a shorter wavelength (i.e., higher frequency) than that of the dye laser, and that the gain medium is ...
Laser pumping is the act of energy transfer from an external source into the gain medium of a laser. The energy is absorbed in the medium, producing excited states in its atoms. When the number of particles in one excited state exceeds the number of particles in the ground state or a less-excited state, population inversion is achieved. In this ...

The process of raising large number of atoms from lower energy to a higher energy level is called pumping. Types of pumping: 1. Optical pumping: which uses strong light source for excitation. 2. Electrical pumping: which uses electron impact for excitation. 3. Chemical pumping: which uses chemical reactions for excitation. 4.
An important factor that limits laser efficiency is that the pump light photons must have higher energy (or the equivalent shorter wavelength) than the laser light. Electrical pumping is another mechanism of excitation that is commonly utilized in gas and semiconductor lasers. In a gas laser, an electrical current flowing through the gas ...
The average power is about 100W/cm 2, peak power 1kW/cm 2. The diode lasers are normally cooled by thermoelectric cooler for low power systems, and by liquid cooling for high powers. Cooling can stabilize the diode laser frequency. There are basically two types of pump geometry, longitudinal pumping (pump beam enters the laser medium along the ...
Current is the pump source. Applications: laser printers or CD players. Dye lasers use complex organic dyes, such as Rhodamine 6G, in liquid solution or suspension as lasing media. They are tunable over a broad range of wavelengths. Gas lasers are pumped by a current. Helium-Neon (He-Ne) lasers in the visible and IR.
