## DEVICE TRADE NAME:

800 Series Surgical Laser System and Accessories

## DEVICE COMMON NAME:

Laser Instrument, Surgical, Powered

## DEVICE DESCRIPTION:

The Laserscope 800 Series Surgical Laser System is currently available in 8 configurations, 7 which have a KTP laser emitting light at 532 nm. This is achieved by passing the infrared beam produced by the Nd:YAG source through a second crystal made from potassium titanyl phosphate (KTP). The process that converts the infrared light to the visible green light requires two photons of infrared light to produce one photon of green light. This conversion process halves the wavelength, or doubles the frequency, so the wavelength of the KTP beam is exactly half that of the Nd:YAG beam.

The Laserscope 800 Series Surgical Laser System (KTP Upgrade) is achieved by an upgraded, higher quality q-switch and driver; increasing the power supply; adding a water to water heat exchanger and utilizing silicone based titanium dioxide lamp reflectors. Four new configurations are available:

- Model 833, 2XP: 50 watts KTP/532, 100 watts Nd:YAG/1064, Dual Port
- Model 834, 2XP: 50 watts KTP/532, 100 watts Nd:YAG/1064, Single Port
- Model 843, 3XP: 60 watts KTP/532, 100 watts Nd:YAG/1064, Dual Port
- Model 843, 3XP: 60 watts KTP/532, 100 watts Nd:YAG/1064, Single Port
