Laser used in medical field is the most important high-tech medical technology in this century, laser medical treatment relates to all clinical disciplines, such as ophthalmology, dermatology, surgery, dentistry, oncology, cancer, etc. Laser has a revolutionary breakthrough in medical treatment, and different wavelengths suit for different therapeutic areas.

Laser Therapy

With free space or fiber coupling output option, usually the power is 5~100 mW for 447 nm blue laser, 5~50 mW for 532 nm green laser pointer and 589 nm yellow laser, both power and frequency can be adjusted individually. Areas of application: External laser therapy, nterstitial laser therapy, intra-articular laser therapy, intravenous laser therapy, pain therapy, photodynamic therapy.

Laser for Ophthalmology

Eyes are the most sophisticated, one of the most important organs. Also eyes are very fragile and vulnerable. Once the eyeball appears lesion, it is difficult to remove the lesion safely by normal surgery. While most organizations of eyes are transparent, which allows the beam to get through. With the development of laser science, people realize to use the laser for eyes treatment, and achieved good results.

Areas of application: retinal photocoagulation, trabecular angioplasty, iridotomy, lamellar keratoplasty, cataract surgery, vitreous Lysis. Normally several millijoules are needed for pulsed laser, such as 2 mJ for 532 nm laser and 10mJ for 1064 nm laser. The power is around several watts such as 2 W, 3 W for 532 nm green laser.

Laser for Dermatology

Laser for dermatology treatment has also made rapid progress over the past decade. In Europe, America, Japan and other countries, dermatologic surgery uses non-intervention type of treatment to achieve a good therapeutic purposes, instead of traditional surgery, transurethral resection, skin grafting and other technologies. Currently, the laser has been widely used in in varieties of skin and beauty items.

Normally single pulse energy for pulsed laser needs hundreds to thousands millijoules such as 400 mJ for 532 nm, 800/ 1600 mJ for 1064 nm with several hertz Rep.rate. Areas of application: vascular lesions, pigmented lesions, onychomycosis, tattoo removal, hair removal, laser resurfacing.

Laser for Surgery

Laser surgery uses laser pointer light to remove diseased tissues or treat bleeding blood vessels. Laser surgery may also be used to remove wrinkles, sunspots, tattoos, or birthmarks. Areas of application: oncology (cancer treatment), varicose veins, gallstones, lithotripsy, urological surgery, gynecological surgery. Especially the double pulsed frequency doubling laser type with 532 nm and 1064 nm combined for 120 mJ/ 160 mJ of single pulse energy, 240/ 320 mJ of double pulse energy.
