A dual-wavelength Q-switched Nd:YAG laser emitting at 1064 nm and 532 nm and an Er:YAG laser were tested on a range of feathers containing melanin, carotenoids and psittacofulvins. In a cataract operation, we replace the cloudy lens from your eye (the cataract) with an artificial lens. This is sometimes called a "secondary. 3. Here, we report the case of a patient who sustained Nd: YAG laser macular injury with subsequent 6 year follow-up evaluation. 5 mJ pulse. Abstract. Here, we report an injection-seeded, PRF changeable single-frequency Ho:YAG laser with PRF changing from 150 to 750 Hz, which is the highest PRF ever obtained in a Ho:YAG single-frequency laser. We encourage you to speak to your eye doctor about possible risk factors and whether you are in need of this procedure. M. These lasers have many different applications in the medical and scientific field for processes such as Lasik surgery and laser spectroscopy. Laser fibers of 150 µm length were.
