New Beauty Technology: 1550/1927 Thulium Erbium Fiber Laser

May 10, 2024

The beauty market is changing with each passing day. Traditional beauty techniques have become widespread and common, and new beauty instruments are urgently needed to change everything.

In the current beauty market, laser aesthetics has a large proportion, but the core of laser machines is the laser bar (laser source). Industrial lasers are roughly divided into four types. The laser medium or structure, oscillation wavelength, excitation source, etc. used are different. The laser medium is a substance containing atoms that can convert the energy of the excitation light into laser light, and the types of lasers are classified according to the medium.

Today, we will introduce the latest fiber lasers that are hot in the beauty market: thulium fiber laser (1927nm) and erbium fiber laser (1550nm).

What is Fiber Laser?

Fiber laser uses optical fiber as a medium and is the product of the development of interrupt amplification technology for long-distance communication into high-power output laser. Optical fiber consists of a core that transmits light in the center and a metal cladding that concentrically covers the core. Fiber laser uses this core as a laser medium to amplify light.

The structure of fiber laser is generally a pulse light called Seed Light generated by Seed LD, which is then amplified by two or more fiber amplifiers. The excitation LD is equipped with multiple single-tube emitter (one light-emitting layer) LDs. Each LD has a low power output, so it has the advantage of less heat load and achieves a long life. In addition, the more LDs there are, the higher the power output laser can achieve. Fiber laser oscillation efficiency is high, and it has the characteristic of lower power consumption compared to solid lasers and gas lasers.

The amplification fiber (preamplifier, main amplifier) has a three-layer structure, including a core and two metal claddings. The excitation light enters the inner metal cladding (inner cladding) and the Yb-added core, and the atoms inside the core are transformed into excited states. The laser is confined in the core and moves forward, and then amplified by exciting atoms. The further it moves in the medium, the stronger its intensity becomes. Unlike solid lasers or gas lasers, light moves in one direction and does not go back and forth.

What is Thulium Fiber Laser?

Thulium fiber laser is a fiber laser that uses thulium as a gain material. It transmits laser energy through optical fiber to achieve cutting and ablation of tissues. Its unique wavelength and energy characteristics enable it to ensure cutting (vaporization) efficiency during surgery while accurately controlling the cutting depth and range to reduce damage to surrounding tissues.

Thulium laser (Tm: YAG laser) is an advanced new laser with a tissue penetration depth of only 0.2mm and a coagulation layer depth of about 1mm. It does not damage deep tissues, has high vaporization cutting accuracy, and is safe.

1927nm thulium laser often used for anti-aging, skin rejuvenation and hair regeneration.It opens skin micro-channels, introduces functional products, and maximizes product effects.

1927 Thulium laser is a long-pulse infrared laser. It emits light in fractional scanning mode. The main target color base of thulium laser is water, but melanin and hemoglobin in the skin also absorb laser energy. It belongs to the category of non-ablative and micro-ablative treatment. Its effect on the skin is a true-epidermal effect. The heat accumulation and temperature rise in the dermis are higher than those in the epidermis. The penetration depth of thulium laser is deeper, and the thermal diffusion effect of the skin is obvious. It is one of the important instruments in 3D mesodermal whitening and anti-aging therapy.

What is Erbium Fiber Laser?

Non-ablative 1550 nm fractional laser is a new type of laser treatment technology. Its laser transmits energy in a fractional output mode, which can stimulate collagen fibers and elastic fibers, thereby achieving self-repair and reconstruction of the skin. It has the advantages of less damage to skin tissue, fast recovery, less pain for patients during treatment, and mild adverse reactions such as facial pigmentation after treatment.

The working principle of erbium fiber 1550nm fractional laser is to generate a tiny light beam through the 1550nm band fractional laser, which forms multiple tiny thermal damage areas after acting on the skin. The skin activates the self-repair mechanism due to the damage and stimulates collagen regeneration, thereby achieving the effect of skin rejuvenation, skin beautification and skin rejuvenation.

1550nm erbium laser has the functions of repairing enlarged pores, solving skin photoaging, treating shallow acne pits and scars, and improving sebaceous gland secretion.

1927nm & 1550nm Thulium Erbium Fiber Laser

Liton Laser combines 1927nm thulium laser and 1550nm erbium laser to produce the latest fiber optic beauty technology on the market: thulium erbium dual-wavelength laser!

The 1550nm/1927nm dual-wave laser was first developed by Fraxel in the United States. Since both are fiber lasers and are non-ablative to micro-ablative treatments, they are both fractional lasers and the treatment range is also overlapping. LitonLaser found that when high-energy 1550nm erbium laser treatment is used first, followed by 1927nm thulium laser treatment immediately, and finally applying skin care products, the treatment effect is very obvious. Especially for acne treatment, for severe acne, a dual-wave combined treatment can produce obvious before and after treatment photos.
