 So that green laser pointer can be used for a longer time.
Holmium laser with a wavelength of 2.1μm, exactly in the water absorption value, the laser energy efficient absorption of the water in the stone and organizations, crushed stones by micro-blasting of the water molecules and vaporization of soft tissue. The feature requires direct contact with the object of treatment, energy attenuation in the water environment. In order to improve the output power, often using multiple laser crystals arranged in a matrix to increase the power, and thus power, cooling, there are special requirements, maintenance costs are also higher. Green laser wavelength of 532nm, which is characterized by it can be a large number of oxyhemoglobin absorption, while the water is almost absorbed. This makes the system in the liquid environment of vaporization of soft tissue, non-contact manner, while its high-energy not consumed in the water. When using green laser pointer , the customer should operate in the correct and suitable procedure.
The classification of green laser pointer can be performed as per different classification standards
Often improve the output power laser pumped, complex resonator optical design system to improve the output power at the same time will produce a lot of heat, which requires a certain ambient temperature and good heat dissipation effect, thereby protecting the stable operation of the equipment. Wavelength of 2 μm thulium laser characteristics and the holmium laser is very close, we can say yes Description: the improvement of the holmium laser laser (U.S. FDA 510K K033423). Thulium laser can be the organization of water molecules effectively absorb, but not for the oxyhemoglobin absorption. Thulium laser uses a continuous wave output mode is different from the holmium laser pulse mode. Features the same request direct contact with the object of treatment, the energy attenuation in the water environment. Using time of green laser pointer can be prolonged with the suitable and appropriate maintenance.
Enhance the output power is also green laser pumped cooling requirements will increase with the increase of output power. The 980 nm red laser FDA-approved in 2007, which uses new nano-pole multi-element semiconductor crystal laser system, a single-lens optical system, nano-scale fiber-coupled system and computer control systems. Not only that, Biolitec red laser to make this four-part a perfect combination of an organic whole, has been unprecedented for organizations to cut vaporization speed, clinical safety, and ground-breaking clinical-functional applications and meet the future needs of the medical laser research. From the red laser wavelength characteristics: In the past, are a single laser to be absorbed by hemoglobin or water molecule.
