Solid-state laser

Solid state laser - This is a laser that, unlike gas lasers, uses a solid-state active medium. Various glasses and crystals activated by rare earth elements are used as this active medium.

Solid-state laser They are characterized by very high efficiency, and some models are quite compact. One such laser is the DPSS model, which is becoming increasingly popular. A distinct advantage of this laser model is its high-quality beam, taking into account monochromaticity and focusing. They also have a narrower wavelength range and significantly lower beam divergence. The advantages of DPSS lasers include a simpler and less expensive design, small size, high resistance to damage, and a service life of over 10,000 hours. In general, the wavelength solid-state lasers The wavelength ranges from the UV to mid-IR regions. These lasers operate in pulsed, continuous, or quasi-continuous modes.

Generated solid-state lasers A three- or four-level design. The active element is a circular cylinder, or sometimes a rectangular rod. In rare cases, the active element has a more complex configuration. When a large working fluid is used, several pump lamps are used around the fluid to achieve uniform excitation. Ned ions are particularly common activators for materials.³⁺.

Lasers based on neodymium-doped phosphate and silicate glasses, which convert radiation in the region of 1.05 µm, are widely used in engineering and science. Using lasers based on such glasses allows for the generation of more powerful pulses. Active elements made from such glass are characterized by high optical quality and can have a large volume for a given element shape.

Solid state lasers, Equipped with neodymium phosphate glass, these lasers produce the most active pulses. Yttrium aluminate and lithium fluoride crystals are also widely used. These lasers play a key role in the development of laser processing, offering significant operational advantages.

Solid-state laser It has significant advantages over a gas laser. For example, it can be used on structural steel of any thickness. It handles thin ferrous and stainless steel accurately, leaving a clean edge. It can cut thin aluminum and handle non-ferrous metals with high quality.

Solid-state lasers They are increasingly used in various areas of life and production. They are used not only for high-quality metal cutting but also for high-quality welding. They are used in new electronic device technologies, medicine, and optical data processing. They are also used in integrated and fiber optics, laser spectroscopy, laser chemistry, nonlinear optics, high-speed photography, seismographs, and various physical instruments.
