Introduction

What Is A Long Pulsed Nd:YAG Laser?
  An Nd:YAG laser is a solid state laser capable of producing a near-infrared wavelength that penetrates deep to the skin and is readily absorbed by hemoglobin and melanin chromophores. The lasing medium of Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) is a man-made crystal (solid state) that is pumped by a high intensity lamp and placed into a resonator (a cavity capable of amplifying the power of the laser). By creating a variable long pulse duration and an appropriate spot size, it is possible to significantly heat deep skin tissues, such as large blood vessels and vascular lesions.
  The Headpiece is fine designed, and the laser spotsize can be adjusted from 8-16mm diameter, and a continuely headpiece cooling is cool the skin to get down skin tempreture, all that will enables the treatment much more convinent, comfortable and efficient.
  The pulse width can be adjusted from 5-100ms, and the long pulse width can treatment the hair follicle more efficiently.So the headpice slids over the skin the same time the hair burns off. So a super quick hair removal can be achived.
  Compared with other devices for hair removal, pulse width can be selected to burn the hairs much more efficiently; and the spotsize can be ajusted by 8-16mm diameter, so the bikini hairs removal will be suitable and easy operate. Also the efficience is immediately and visiable, as through goggles (which is used to protect eyes.) the operate can see that the hairs burns into ashes.
  The 755nm Alexandrite Laser provides permanent hair reduction for skin types 1 through 4.
  The system is based on alexandrite technology which is superior to other wavelengths in providing permanent results.
  Faster Treatments – With an 18 mm spot size treatments are quick. The underarms can each be treated in less than 2 minutes. Thereare no gels to apply and topical anesthetics are normally not needed, saving even more time.
  More Flexibility – The 755nm Alexandrite Laser also comes with an 8 mm spot size that allows more flexibility in the areas being treated, such as the nose and ears.
  Multiple Applications – Also capable of treating pigmented lesions including sun and age spots, freckles, cafe-au-lait and melasma; and vascular lesions such as leg veins.More Comfort for Patients -The unique DCD cryogen cooling system offers safe and consistent cryogen spray protection for greater patient safety and comfort. Additionally, this means there are no cooling gels to apply before the treatment.

Alexandertite Laser Hair Removal 755nm is commited to the gold standards for hair removal, due to the effective melan absorbtion, and the less side effects.
Alexanderite Laser Hair Removal 755nm is based on the principle of selective light and heat, through a reasonable adjustment of laser energy and pulse width, laser can penetrate the skin to reach the hair follicles, and laser energy is absorbed and then transformed into heat by the hair follicle tissue, so that the hair loss of regenerative ability and from the surrounding tissue, so the hair will be removed permanently.

Theory

How Does A Long Pulsed Nd:YAG Laser Work?
  Nd:YAG laser energy is selectively absorbed by the deeper levels of the dermis and allows for treatment of deeper vascular lesions such as telangiectasias, hemangiomas and leg veins. The laser energy is delivered using long pulses which are converted into heat in the tissue. The heat impacts the vasculature of the lesions. In addition, the Nd:YAG Laser can treat at a more superficial level; by heating the subcutaneous skin (in a non-ablative manner) it stimulates neo collagenesis which improves the appearance of facial wrinkles.
  Treat leg veins with long-pulsed 1064-nm light. The Nd:YAG 1064 laser handpiece coagulates and destroys large, deep, yet cosmetically unacceptable blood vessels and leg veins without the use of chemicals or needles. This easy-to-use, ergonomic handpiece effectively coagulates oxygenated reddish telangiectasias, as well as deoxygenated bluish venule ectasia and reticular veins up to 4 mm diameter.
  The long-pulsed 1064 nm Nd:YAG laser is able to penetrate deeper into the skin than lasers that use shorter wavelengths of light. This enables treatment of deeper vascular lesions such as reticular veins, deeper spider veins, hemangiomas and leg veins than can be targeted with other lasers.
  Alexandrite laser 755nm &long pulse nd Yag 1064, the best absorption peak of melanin wavelength, direct specific role in the hair follicle in the melanoma cells, especially strong ability to hair, especially for dense hair and skin color partial black hair removal.
Large spot, high speed, shorten the treatment time 4-5 times. Ten minutes in addition to large area hair removal, 3-5 minutes to remove small areas of hair, especially for large area hair removal.
  More secure, unique DCD “laser cooling function” completely avoid the “contact cooling” may cause skin burns, the hair removal process more convenient and comfortable.
  Hair removal at the same time, both contraction of the pores, and promote skin collagen protein newborn effect. Do not worry about hair removal after gross pores, dry skin problems.
  DCD cryogen cooling and Semiconductor cooling hair removal machine are freezing the air through technological innovation so that the air coming from the treatment head can become -the 20-Celsius degree to better protect the skin, unlike other laser burns the skin.
  755nm specific wavelength laser absorbs hair follicle melanin, and the heat to destroy the hair follicle.
  The laser energy can be shot down into the hair follicles and the hair follicle is destroyed so that the hair follicles stop growing.

FAQ

Q1: Why we choose a long pulse laser for hair removal?
A: As most known, long pulse ND YAG laser can create laser pulse with super high energy, much higher than other lasers and IPL. So long pulse laser can removal hair and around tissues completely, and also is efficient for tiny slight hair removal, and other skin diseases treatment.

Q2: Why your machine use fiber to conduct the laser, not directly laser shooting?
A: Three facts:
  1. the laser generator is so big size that we just can not put into a headpiece.
  2. for directly laser shooting, the spot size depends on the diameter of laser crystal, so the max spot-size is nearly the same size as laser crystal. To use fiber conduct laser pulse, the spot-size can reach 12mm diameter.
  3. as the laser generator put inside of machine, so the headpiece can be designed light and small, much easy to hold by hand.

Q3: How to avoid skin burning as the laser energy is so high?
A: Headpiece cooling.
