Description

Q-switched Nd:YAG laser System of Skin treatment with Nanosecond Pulsed and Picosecond Pulsed band

The present invention relates to a Q-switch NDYAG laser system for skin treatment having nano-pulse and pico-pulse bands, and more particularly, it treats the pigment region with nano-pulse band, and further realizes pico-band in one equipment system Therefore, it was possible to treat the pigment area, so that two pulse bands were implemented in one device to treat various areas of the pigment treatment area and to minimize the side effects.

The conventional NDYAG laser is a tattoo removal laser, which was introduced to domestic dermatology in the early 2000s and has been developed to treat melasma.

Q-Switch NDYAG laser is basically composed of optical resonator, power supply and cooling device.

The internal configuration of the optical resonator uses a flash lamp as a pumping light source to induce and emit a Rad crystal of the ND YAG medium to generate a laser.

When energy is delivered by the energy source of the flash lamp to the NDYAG medium (a synthetic crystal of Yttrium-Aluminum-Garnet doped with Neodymium 1.1%) in the resonator, the atoms in the safe state are changed to an excited state, amplified in the resonator, and laser light is emitted. .

It has a wavelength of 1064nm inside and a delivery device specially coated with 1064nm outside to treat the affected area.

The wavelength of 532nm is made by passing the KTP (Potassium Titanyl Phosphate) crystal through the internal resonator, and the wavelength is halved and the frequency is doubled (Frequency-doubled).

On the other hand, most of the equipment using the Q-switched NDYAG laser used for skin treatment has a nano-band. In order to selectively remove chromophores in the skin, the dye laser needs a relationship between the wavelength and pulse duration of the laser. In the NVIDIA laser, a wavelength of 1064 nm is used, and a wavelength of 532 nm is used as the second harmonic. This is a wavelength band that can be removed based on most of the melanin pigments distributed in the epidermis and dermis, and the melanin pigments are removed due to the *thermal relaxation time by the pulse width of the pulse duration. Currently, most of the laser market in the pigment area is using the nano band, and it can be purchased at a lower price than the pico band. . In other parts, the nano-band thermal relaxation time has made it easy to remove the melanin pigment distributed in the epidermis and dermis, but it cannot be completely removed at once or damage the epidermis to remove the pigment and damage the surrounding blood vessels. (bleeding) leads to the accompanying treatment, which has the disadvantage of lengthening the recovery period after treatment.

However, when the pulse band is irradiated in the pico band, *thermal relaxation time can cause more various lesions than the nano band, it is possible to remove the melanin pigment distributed in the epidermis and dermis at once, and it minimizes damage to the epidermis and peripheral blood vessels The operation can be performed without damage to the There is an advantage in that the recovery period after treatment is also shortened. However, constructing an optical system in the pico band has a disadvantage in that it is expensive because more costs are added than in the nano band.

Therefore, in the present invention, by proposing a Q-switch NDYAG laser system for skin treatment with nanopulse and picopulse bands, various modes with different pulse bands are provided for possible and effective treatment of simultaneous oscillation or time difference oscillation. This is to suggest the NDYAG laser system for skin treatment that can improve the treatment effect and treatment efficiency, shorten the treatment time, and minimize the side effects after treatment.

That is, it serves to return all the light sources generated from the active medium to the active medium.

The first lambda/4 lens 110 is formed between the first total reflection lens and the first pocket cell, and constitutes a motor unit on one side, so that it moves according to the operation of the motor unit.

That is, when the motor unit is operated, it moves sideways so as not to interfere with the movement path of the laser beam.

In addition, the first lambda/4 lens 110 is formed to transmit a wavelength of 1064 nm (AR@1064 nm on the S1 and S2 surfaces), and serves to help switch the laser beam together with the first pocket cell.

a fifth mode in which the motor unit formed in the first lambda/4 lens 110, the motor unit formed in the KTP crystal 160, and the motor unit formed in the second lambda/4 lens 210 do not operate;
The first lambda/4 lens 110 and the second lambda/4 lens 210 are lasered by operating the motor unit formed on the first lambda/4 lens 110 and the motor unit formed on the second lambda/4 lens 210 . a sixth mode to deviate from the path of the beam;
The first lambda / 4 lens 110 and the motor formed in the KTP crystal 160 are operated so that the first lambda / 4 lens 110 and the KTP crystal 160 are separated from the path of the laser beam. 7 mode and
Operation with reference to any one mode except for the fifth mode among the eighth modes for operating the motor unit formed in the second lambda/4 lens 210 to move the second lambda/4 lens 210 away from the path of the laser beam A NDYAG laser system for skin treatment using a stable resonator and an unstable resonator, characterized in that a signal is provided to each motor unit, or an operation signal is not provided to each motor unit in the fifth mode. The method of claim 1,
of the first VRM output mirror 150,
