Green Light Laser Wavelength

Solid state frequency doubled.

Green light laser wavelength.

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation the term laser originated as an acronym for light amplification by stimulated emission of radiation. Built on the greenlight hps system the greenlight xps system increases the power and area of the laser beam by 50 providing a wider tissue vaporization effect without sacrificing depth of vaporization or coagulation. Pulse modulated by 12 hz 25 duty cycle. 2 7 to 2 9 μm for hydrogen fluoride 80 atmospheric transmittance.

This laser utilizes a diode pumped nd yag laser light that is emitted through an lbo instead of a ktp crystal resulting in a higher powered 532 nm wavelength green light laser while still using the same 70 degree. The 532 nm wavelength closely approximates a hemoglobin absorption peak and is therefore well suited for the treatment of superficial blood vessels. 1 its 532nm wavelength vaporizes prostate tissue without charring and limits penetration leaving a thin rim of coagulated tissue that aids in hemostasis. The popular red laser has a wavelength of 650 nanometers that our eyes perceives in the visible spectrum as red.

That s right this sucker s a class iv laser and can be dangerous for the human eye from more than 200 meters away. Blue violet presentation pointer. 33 9 meters mpe 1x10 3 w cm 2 eye protection. The first laser was built in 1960 by theodore h.

Quasi cw 15 khz 25 khz coagulation beam mode. Flashblindness glare and distraction. The energy of a single photon is a small number because the planck constant is ridiculously tiny. Nominal optical hazard distance nohd.

The human eye is most sensitive to green light of 555 nanometers. But wavelength does affect the three visual interference distances. The ktp laser is a frequency doubled nd yag laser that emits green light at a wavelength of 532 nm. Used in research for laser weaponry operated in continuous wave mode can have power in the megawatt range.

Chemical reaction in a burning jet of ethylene and nitrogen trifluoride nf 3. Maiman at hughes research laboratories based on theoretical work by charles hard townes and arthur. However green light has even more energy in a wavelength of a minuscule 532 nanometers. They weren t fooling around when they designed it like a lightsaber.

The energy of a single photon of green light of a wavelength of 520 nm has an energy of 2 38 ev. In 2006 the 120w lithium triborate laser lbo also known as the greenlight hps high performance system laser was introduced. You can use the photon energy calculator to further explore the relationship between the photon energy and its frequency or wavelength. Laser gain medium and type operation wavelength s pump source applications and notes hydrogen fluoride laser.
