Product Overview
Professional 755nm Alexandrite laser machine
The 755nm Alexandrite laser machine is a top-of-the-line laser hair removal device, highly regarded in the aesthetic treatment field, suitable for hair removal and a variety of other applications. Unlike conventional diode lasers, the 755nm fiber laser hair removal machine places the laser generator inside the machine, rather than in the handle. Therefore, energy and heat are delivered via the optical fiber. With this 755nm hair removal machine, you can permanently remove unwanted hair.
While conventional diode laser handles are bulky, expensive, and easily damaged, the professional 755nm fiber laser hair removal machine is lightweight and robust, offering unlimited shot counts, durability, and no consumables. Its comprehensive range of professional specifications meets the needs of a wide range of users. It features a unique Alexandrite laser wavelength and an adjustable spot size from 4mm to 18mm, offering consistent performance and versatility for a wide range of applications, including mole removal, hyperpigmentation, and pain relief.
Application
The QM-755 Alexandrite laser machine is versatile and can effectively address a variety of cosmetic concerns. It excels in hair removal due to its effective absorption of melanin and client response and possible side effects vary. It can remove unwanted hair from various areas, including the face, arms, underarms, chest, back, bikini line, and legs. Whether hair is light, sparse, coarse, or dark, this laser delivers impressive results.
The Alexandrite laser machine also minimizes pore size and promotes collagen regeneration, eliminating the need to worry about enlarged pores and dry skin after hair removal. Its wide range of spot sizes, from Ø 4 to 18mm, is particularly noteworthy, making it specifically designed for the treatment of unwanted facial hair.
Whether you have fair skin (types I-III) or darker skin, the QM-755 Alexandrite laser utilizes the powerful energy of the 755nm Alexandrite laser wavelength to provide safe, optimal, and long-term hair reduction results for every area of your body.
The Alexandrite laser machine is suitable for all hair types: lip hair, beard hair, chest hair, underarm hair, back hair, arm hair, leg hair, and unwanted hair outside the bikini line.
It is suitable for a range of skin types with settings selected by a trained operator (I, II, III, IV, V, VI). It is designed for improved treatment comfort, non-invasive, and has client response and possible side effects vary.
- Hair removal on all skin and hair types
- Spider veins
- Telangiectasia and telangiectatic matting on the face and legs
- Nail fungus treatment
- Removal of epidermal pigmented lesions (Sun-damaged skin, Age spots, Freckles)
- Treatment of vascular anomalies
755nm Alexandrite laser machine Working Principle
Alexandrite laser technology is based on the principle of selective photothermal therapy. By rationally adjusting the laser energy and pulse width, the 755nm wavelength laser light penetrates the skin and reaches the hair follicles. The laser energy is absorbed by the follicle tissue and converted into heat, causing the hair to lose its ability to regenerate and separate from the surrounding tissue, thus achieving long-term hair reduction.
The 755nm Alexandrite laser utilizes a unique laser technology called Alexandrite crystal laser technology. This technology utilizes Alexandrite crystals as the laser medium, effectively emitting light at a wavelength of 755nm. This wavelength is particularly suitable for hair removal and other dermatological procedures:
It has a high absorption rate for melanin, low damage rate, uniform energy distribution, long service life, and easy maintenance.
Advantages of the QM-755 Alexandrite Laser
1.High-quality Alexandrite laser wavelength:755nm wavelength effectively targets melanin and damages hair follicles, achieving long-term hair reduction while managing exposure to surrounding tissue. Treatment time is short and designed for improved treatment comfort, suitable for all skin and hair types. Furthermore, this technology enables a more focused beam (collimated light), avoiding wasted energy on untreated areas and supporting the commonly used treatment in the shortest possible time.
2.Lightweight handle:The operator can use a lightweight, low-temperature handle equipped with a DCD cooling tip, supporting fatigue-free use even for hours, and a designed for improved treatment comfort and comfortable treatment experience for the patient.
3.Advanced Cooling System:Utilizing the DCD professional cooling system, the temperature can reach -5°C, keeping the skin cool during treatment. This ensures no damage or discomfort to the epidermis, maximizing comfort and minimizing side effects.
4.Expert Operating System:Adjustable pulse width, energy density, and spot size allow for customized treatment plans based on individual needs, supporting optimal results.

QM-755 Alexandrite Laser FAQs
▶ What is a 755nm Alexandrite Laser?
The 755nm Alexandrite Laser uses alexandrite crystals as its laser medium. It emits laser light at a specific 755nm wavelength, targeting the melanin in hair follicles, heating and destroying it, thereby preventing hair regrowth and achieving long-term hair reduction.
▶ What is the difference between a conventional diode laser and a fiber-based 755nm Alexandrite Laser?
The 755nm Alexandrite Laser uses a special laser technology called alexandrite crystals as its laser emission medium. This crystal is capable of efficiently emitting light at a wavelength of 755nm. However, conventional diode lasers mostly use a vertical laser stack structure, consisting of multiple diode bars arranged in a stacked pattern. These bars are then combined using an optical system to create a high-power, uniform output beam.
▶ Why use a fiber-based Alexandrite Laser machine for hair removal?
The laser's energy emission area is circular, with sharp boundaries and uniform intensity distribution, eliminating duplicated or missed areas. This allows the machine to be as efficient as the operator. By using alexandrite crystal as the laser medium, maintenance becomes easier, faster, and cheaper, and with no consumables, the lasers have a very long lifespan.
▶ Do you offer OEM and ODM services?
Yes, we can offer you consistent OEM and ODM services. We have our own R&D department, several experienced designers and engineers, and multiple production lines, enabling us to provide you with high-quality aesthetic laser equipment tailored to your needs, ideas, and samples.
Technical Advantages of 755nm Alexandrite Laser
High Melanin Absorption– The 755nm wavelength is highly effective at targeting melanin, the pigment in hair. This high absorption makes the Alexandrite laser particularly suitable for removing light and fine hair in individuals with light to olive skin tones (Fitzpatrick skin types I-III).
Speed and Efficiency– Alexandrite lasers typically feature a larger spot size and a higher repetition rate, allowing for rapid treatment completion. This is particularly beneficial for treating large areas such as the back, legs, and arms, as it reduces the total time patients spend in treatment.
Effectiveness on Light and Fine Hair– While many laser types are effective for removing coarse hair, the specific wavelength of the Alexandrite laser makes it one of the few lasers that can also effectively remove fine and light hair, which can be challenging with other laser systems.
Cooling– Many Alexandrite laser systems are equipped with integrated skin cooling to help reduce the discomfort of laser treatment. Cooling also helps protect the skin's surface, reducing the risk of thermal damage.
