Laser Hair Removal Technologies
The key to successful laser hair removal is the delivery of high energy to the skin so that it is selectively absorbed by the melanin surrounding the hair follicle, while protecting the surrounding tissue.
The principle of laser hair removal is to apply a specific wavelength of light and pulse duration to the melanin in the hair follicle, while avoiding the surrounding tissue area, to ultimately achieve hair removal.
Melanin is the pigment associated with color and is naturally found in our skin and hair.
What is Fiber Laser Hair Removal Machine
The light produced by multiple diode lasers is coupled into a single core multimode fiber through an array of miniature lenses to deliver the light to the target location – this is how Fiber laser hair removal machines work. Fiber laser hair removal devices are characterized by low damage rates, uniform energy distribution, long life, and ease of maintenance.
What is Diode Laser Hair Removal Machine
The diode laser uses a single wavelength of light that has a high absorption rate for melanin. It also incorporates skin cooling to protect the skin surface. As the melanin heats up, it destroys the root and blood flow of the hair follicle and permanently disables the hair. The diode laser has the ability to deliver high-frequency low-flow pulses and can be used safely on all skin types.
Differences Between Fiber Laser and Diode Laser Hair Removal Machine
1. Laser Array
Fiber-coupled diode laser machine (Fiber Laser Hair Removal machine) produces light that is coupled by multiple diode lasers through an array of microlenses into a single-core multimode fiber in order to deliver the light to the target site. However, the most common diode lasers are vertical laser stacks with many diode bars which are arranged in stacks. The fiber laser chip is welded to a heat sink to provide high output energy.
2. Obtaining medium materials
The materials used for the transmitting lasers of the two lasers are different. The gain medium used in a fiber laser is optical fiber. In contrast, the gain medium used in a diode laser is a semiconductor material. For example, it is usually gallium arsenide, indium gallium sulfide, etc.
3. Laser lifetime and handpiece
The laser lights of a fiber-coupled diode laser machine are not in the handle. They are in the body of the machine. So the heat is concentrated in the core, not in the hands. The cooling system does less work to dissipate this heat. As a result, the laser is more durable, about 3 years.
Diode laser have stable voltage output control and a superb water cooling system. The stack life of a diode laser is about 2 years.
Advantages of Fiber Laser Hair Removal Machine
Compared to diode laser hair removal machines, this fiber laser hair removal machine has a longer light focal length and less astigmatism, allowing for faster treatment of large areas and a built-in cooling system for truly comfortable and painless hair removal.
1. The laser energy is more focused and has less astigmatism.
2 The laser has a longer light output life, fiber laser has 50 million shots, and diode laser hair removal machine only 20 million shots.
3. Better heat dissipation, the construction of the fiber laser machine requires relatively little cooling system and can be used for a longer period of time. The handle of the diode laser is easy to burn out and more expensive to maintain.
4. The laser bar of the fiber laser hair removal machine is inside the machine and the handle is lighter and easier to grip.
5. The size of the fiber laser hair removal machine can be made smaller for the same energy output, resulting in lower shipping costs.
