31. This was followed by the MS-Series of Nd : YAG laser systems, designed for industrial welding, cutting and drilling applications. 32. In podiatry, the Nd : YAG laser is being used to treat onychomycosis, which is fungus infection of the toenail. 33. LIDAR laser is a passive Q-switched Nd : YAG laser with the dual wavelengths of 1064 nm and 532 nm. 34. This is the Erbium : YAG laser which causes five to 10 times less heat injury to the underlying tissues. 35. An Nd : YAG laser ( 1064 nm wavelength ) is a common choice of laser for working with biological specimens. 36. Typical laser systems used in APLI are Krypton fluoride laser ( ) and frequency quadrupled Nd : YAG laser ( ). 37. Using hysteroscopy the Nd : YAG laser has been used for removal of uterine septa within the inside of the uterus. 38. The new system also replaced the Nd : YAG laser rangefinder used in the Hughes unit with a composite Chobham armour. 39. The LPwC process utilizes low energy, high frequency Nd-YAG lasers producing pulse energies of and pulse durations of, using spot sizes diameter. 40. Holmium : YAG lasers have wavelength of 2100 nm ( infrared ) and are used for medical procedures in urology and other areas.
