Areas of application:

• ■ External laser therapy
• ■ Intra-articular laser therapy
• ■ Pain therapy
• ■ Interstitial laser therapy
• ■ Intravenous laser therapy
• ■ Photodynamic therapy

Common wavelengths:
447nm, 532 nm, 589 nm, 655 nm, 810 nm...

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 and 589 nm yellow laser, both power and frequency can be adjusted individually In medicine, lasers allow surgeons to work at high levels of precision by focusing on a small area, damaging less of the surrounding tissue. If you have laser therapy, you may experience less pain, swelling, and scarring than with traditional surgery. However, laser therapy can be expensive and require repeated treatments.

Areas of application:

• ■ Retinal photocoagulation
• ■ Iridotomy
• ■ Cataract surgery
• ■ Trabecular angioplasty
• ■ Lamellar keratoplasty
• ■ 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. 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. 

Common wavelengths:
532 nm, 561 nm, 577 nm, 635 nm, 671 nm, 810 nm, 980 nm, 1064 nm, 1320 nm...

Areas of application:

• ■ Oncology (cancer treatment)
• ■ Gallstones
• ■ Lithotripsy
• ■ Urological Surgery
• ■ Gynecological Surgery
• ■ Varicose Veins

Laser surgery uses laser 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:
