1, solid state lasers and gas lasers of the earliest development, these two kinds of laser output power is large and stable, easy to use, high efficiency, less consumables (frequency).
2, liquid laser includes a variety of dye laser, the working substance is rhodamine, carbonation cyanine dye is dissolved in a solvent such as alcohol or chloroform, etc., to form a solution, by high speed cycle, the dye from a thin nozzle, forming optical liquid level good, pumping light through a certain angle mirror placed pumped, hit the level the dye, stimulated to produce laser. The advantages of dye lasers is the work material, large output power, optical properties. The disadvantage is the need to constantly replace dye, more supplies, maintenance complex, efficiency (low frequency).
3, the semiconductor laser is a semiconductor material is a kind of laser working material, it has the merits of small volume, low price, high efficiency, long service life, medical industry research more and more designers attempt to substitute other laser with semiconductor laser, as the main measure to improve the laser medical instrument.
1, the CW laser is in a stable, continuous beam of the laser energy release. Pulsed laser energy is released in a pulse form, on the basis of pulse width.
2, the semi continuous laser is in the form of impulses to release energy, the difference is between each pulse interval time is very short, also can not be adjusted, the laser energy is released to the close connection in the pulse group form together (such as pulse copper vapor laser with 6000 per second to 15000 pulse groups release in fact, the skin), difficult to "identify" that this is a pulsed laser, its clinical effect and continuous laser similar effects, so sometimes will also be semi continuous laser called quasi continuous laser or quasi CW laser.
3, pulse laser can be divided into long pulse laser (pulse width is in milliseconds) and short pulse laser (pulse width of nanosecond). Short pulse laser including a variety of Q switch laser.
Beauty equipment according to the wavelength range is divided into ultraviolet, infrared, visible light laser
The most used in skin beauty in the field is visible lasers, used in the treatment of vascular lesions and pigmented lesions; second is widely applied for cutting, vaporization lesions and for infrared laser grinding wrinkles; ultraviolet laser used for skin beauty see the less. General description the laser will describe the characteristics at the same time.
