What Is A Long Pulsed Nd:YAG Laser?
You encounter advanced technology when you choose long pulse nd yag laser equipment for your skin treatments. This device uses a unique wavelength of light to target deeper layers of your skin while minimizing risk to the surface. Professionals often recommend it for clients with darker skin tones. You benefit from its precise action, making it a trusted solution for various dermatological needs.
How Does a Long Pulsed Nd:YAG Laser Work?
Wavelength and Pulse Duration
When you use long pulse nd yag laser equipment, you benefit from a device that operates at a wavelength of 1064 nanometers (nm). This wavelength stands out because it penetrates deeper into your skin compared to other lasers. The laser’s energy targets specific structures beneath the surface while minimizing the risk of damage to the outer layers.
You will notice that the pulse duration, or the length of time the laser emits energy, can range from 15 to 30 milliseconds (ms) in most clinical settings. For certain treatments, such as targeting blood vessels of different sizes, the pulse duration may vary from 1 to 10 ms. Longer pulse durations work best for larger vessels, while shorter durations suit smaller targets.
- 1064 nm wavelength reaches deep skin layers.
- Pulse durations typically range from 15–30 ms.
- For vessel treatments, durations can vary from 1–10 ms depending on vessel size.
This combination of wavelength and pulse duration allows you to achieve precise results with minimal discomfort.
Mechanism of Action
Long pulse nd yag laser equipment uses a process called selective photothermolysis. When you undergo treatment, the laser targets specific chromophores in your skin. Chromophores are natural molecules like melanin, water, and oxyhemoglobin. These molecules absorb the laser’s light and convert it into heat.
- The laser energy heats the targeted chromophores.
- This heat destroys unwanted structures, such as hair follicles or blood vessels.
- The surrounding skin remains safe because the laser’s wavelength and pulse duration are carefully chosen.
You experience effective treatment because the laser focuses its energy only where needed. This approach ensures that you get the desired results while protecting healthy tissue.
