Semiconductor laser therapy devices, also known as optical quantum laser therapy equipment, are based on visible light with specific energy levels. This type of laser emits a stream of particles called photons, which is why it is sometimes referred to as a photon quantum laser. Unlike traditional laser therapy devices, semiconductor lasers offer a much higher electro-optical conversion efficiency, resulting in high light extraction rates without generating excess heat. They operate at low voltages and do not require complex cooling systems or water circulation, eliminating issues like overheating, flash damage, or system failure that often occur with conventional lasers.
These devices are compact, cost-effective, and have a long service life. Their therapeutic effects are significant and widely recognized. The SUNDOM-300IB series from Beijing Santon uses multi-wavelength output (650nm/810nm), making it suitable for various illumination techniques. The 810nm wavelength, patented by the company, can penetrate up to 7cm into human tissue, reaching deep layers without causing trauma or pain. With an output power of up to 1500mw, this device delivers effective treatment. It uses GaAlAs semiconductor technology, producing a polarized, monochromatic, directional, and coherent beam—ensuring safety, reliability, and a lifespan of tens of thousands of hours. It offers both continuous and pulsed output modes, enabling fast treatments that take only 10 minutes per area.
**How does semiconductor laser therapy work?**
1. **Anti-inflammatory effect**: The SUNDOM-300IB stimulates immune cells such as T-cells, B-cells, and macrophages, enhancing both non-specific and specific immunity. It helps reduce inflammation and provides analgesic effects.
2. **Improves local blood circulation**: By directly irradiating painful areas or indirectly targeting sympathetic ganglia, it increases blood flow, promotes metabolism of pain-causing substances, and relieves discomfort.
3. **Activates endorphin system**: Laser exposure boosts brain peptide activity, increasing the release of morphine-like substances, thus reducing pain.
4. **Inhibits nerve conduction**: It reduces the speed, intensity, and frequency of nerve impulses, effectively blocking pain signals.
5. **Activates the descending inhibition system**: Laser stimulation sends signals to the spinal cord, helping to suppress pain responses.
6. **Promotes tissue repair**: It enhances new blood vessel growth, stimulates granulation tissue formation, and accelerates protein synthesis, aiding in wound healing.
7. **Biological regulation**: It strengthens immune function, regulates the endocrine system, and balances blood cell activity.
The SUNDOM-300IB series has been clinically validated and is used in various medical fields, including gynecology, urology, and proctology. It includes models such as SD219, SD299, SD266, SD233, SD190, SD130, SD213, SD160, and SUNDOM-300IB/216.
**Key Features:**
- Penetrates up to 7cm into tissues, avoiding absorption by water molecules.
- Provides strong pain relief by blocking nerves and releasing natural analgesics.
- Reduces inflammation, improves circulation, and inhibits bacterial growth.
- Promotes tissue regeneration and enhances cellular metabolism.
- Safe, non-invasive, and free from side effects, making it a green therapy option.
**Is long-term use of semiconductor laser therapy harmful?**
Low-intensity laser therapy is considered a safe, internationally recognized form of treatment. It is non-invasive, painless, and free from infection risks. It has no toxic effects or side effects, avoiding complications like bleeding or infection. Patients with cardiovascular diseases can use it confidently. The biological effects typically peak between days 10–15 and then gradually decline. A standard treatment course lasts 10–15 days, followed by a 5–7 day break before the next session.
