The Alexandrite and Nd: YAG laser machines are widely used in aesthetic treatments, and their key parameters—like energy, fluence, and power—are essential for understanding their performance and ensuring safe, effective treatments.
Energy and Fluence
Fluence is the energy delivered per unit area and is measured in Joules/cm². It determines how much power is applied to the skin during hair removal or rejuvenation. The fluence range can vary depending on the machine and treatment, but typical values for Alexandrite and Nd: YAG lasers might range from 0 to 566 J/cm², with adjustments based on the patient’s skin type and treatment area.
However, advanced laser machines like Torlase can deliver fluence levels between 0 to 3000 J/cm². For safety reasons, it’s recommended to use a maximum fluence of 566 J/cm² during most treatments. At CPMT Laser, we prioritize patient safety, ensuring our machines operate within these limits while delivering effective results.
Power
Power, measured in Watts (W), describes the rate at which the laser delivers energy, impacting the efficiency and speed of the treatment. For Alexandrite and Nd: YAG laser systems, power outputs may range from 500W to over 1000W, depending on the machine’s design and intended usage. These values can vary depending on the specific model and its configuration.

The Importance of Energy in Alexandrite and Nd: YAG Laser Machines
Energy and fluence are crucial in Alexandrite and Nd: YAG laser machines because they directly affect the effectiveness, safety, and overall results of treatments. Here’s why energy plays such an important role:
Targeted Tissue Interaction
Energy and fluence dictate how much power is delivered to the target tissue, such as hair follicles, pigmentation, or vascular lesions. For treatments like hair removal, applying the correct energy level ensures that the laser penetrates deeply enough to destroy the hair follicle without damaging surrounding skin. If the energy is too low, the target tissue may not be effectively treated, resulting in incomplete or ineffective outcomes. Conversely, excessive energy can cause burns, skin damage, or other unwanted side effects.Customization for Skin Types
Different skin types (measured on the Fitzpatrick skin scale) react differently to lasers. For instance, higher fluence levels may be necessary for lighter skin types, as they have less melanin to absorb laser energy, while lower fluence is required for darker skin types to avoid burns or hyperpigmentation. Adjusting the fluence helps practitioners tailor treatments to each patient’s skin tone and hair type, ensuring both safe and effective results.Depth of Penetration
Energy also influences the laser’s ability to reach deeper layers of the skin. Nd: YAG lasers with a longer wavelength of 1064 nm can penetrate deeper into the skin, making them ideal for targeting deep vascular structures or hair follicles in darker skin tones. Proper control of energy levels ensures that the laser reaches the necessary depth without overheating the skin.Treatment Efficiency
Higher energy settings can reduce treatment times by delivering more power in fewer pulses. However, this must be balanced to avoid discomfort or adverse effects. Alexandrite lasers (wavelength of 755 nm) are known for their speed in hair removal, and with precise fluence control, session times can be significantly reduced while still achieving effective results.Safety and Comfort
The energy settings also influence the patient’s comfort. Lower energy levels may be more comfortable for the patient but might require more sessions to achieve the desired results. On the other hand, higher energy levels can deliver faster results, but they also increase the risk of side effects such as burns or scarring if not carefully monitored. The optimal energy settings strike a balance between achieving fast, effective results while ensuring patient safety and comfort.Specific Treatment Goals
Different aesthetic treatments require different fluence levels. For instance:- Hair removal: High energy is needed to destroy hair follicles.
- Vascular lesion removal: Lower energy is used to target blood vessels without damaging surrounding tissue.
- Skin rejuvenation: Moderate energy is used to stimulate collagen production, with minimal downtime.
In conclusion, fluence in Alexandrite and Nd: YAG laser machines is critical for governing how the laser interacts with the skin, determining the effectiveness of treatments, and ensuring the safety of procedures. Proper calibration of energy ensures that treatments are successful while minimizing the risk of side effects.
What is the intensity of the Alexandrite laser?
The intensity of an Alexandrite laser can be explained in terms of its fluence (energy per unit area) and power. Though intensity is not commonly described directly in laser terms, the fluence and power density give a sense of the laser’s strength during treatments.
Key Factors Influencing Intensity:
Fluence (Energy per unit area):
Measured in Joules per square centimeter (J/cm²), the fluence used in Alexandrite lasers for hair removal and other aesthetic treatments typically ranges from 10 to 100 J/cm², depending on the skin type, hair color, and treatment goals.Power:
Measured in Watts (W), power describes how fast the laser energy is delivered. Alexandrite lasers generally operate between 500 to 1000W in clinical settings, though this can vary depending on the specific machine and treatment.
Intensity and Wavelength:
The Alexandrite laser has a wavelength of 755 nm, making it highly effective for targeting melanin in hair follicles and pigmented lesions. Its intensity is particularly suited for light to medium skin tones, as it delivers a high absorption rate in melanin while minimizing damage to surrounding tissues.
How Intensity Affects Treatment:
- Higher intensity (higher fluence) can result in more effective hair follicle destruction but also increases the risk of side effects such as burns or pigmentation changes, especially in darker skin tones.
- Lower intensity settings are often used for finer hair, sensitive areas, or patients with darker skin tones to minimize the risk of complications.
In summary, the intensity of an Alexandrite laser is determined by the amount of energy and fluence delivered over an area and how fast that energy is applied (power). Typical hair removal treatments use fluence levels ranging from 0 to 566 J/cm². Adjustments to power and intensity must be carefully made based on the patient’s skin type, hair color, and treatment area to ensure safe and effective results.
What is the wavelength of the Alexandrite laser?
The wavelength of the Alexandrite laser is 755 nanometers (nm).
This wavelength is in the near-infrared spectrum, which makes it particularly effective for targeting melanin in hair follicles and pigmented lesions. The 755 nm wavelength is ideal for treating light to medium skin tones (Fitzpatrick I-III) and is commonly used for procedures like:
- Laser hair removal
- Pigmented lesion treatment
- Tattoo removal
- Skin rejuvenation
Its high absorption by melanin allows the Alexandrite laser to efficiently target and destroy pigmented structures with minimal damage to surrounding tissues.
