Random Laser Action in Nd:YAG Crystal Powder
This work explores the room temperature random stimulated emission at 1.064 μm of a Nd:YAG crystal powder (Neodymium-doped yttrium aluminum garnet) in a very simple pump configuration with no assistance from an internal mirror. The laser threshold energy as a function of pump beam area and pump wavelength has been measured, as well as the temporal dynamics of emission pulses. The absolute energ...
متن کاملIn vitro Evaluation of Dentin Surface Irradiated by Neodymium-doped: Yttrium Aluminum Garnet Laser (Nd: YAG) Using Scanning Electron Microscopy
Introdouction: Dentinal hypersensitivity (DH) is one of the most painful chronic problems reported in dental offices. Various methods have been applied for the treatment of DH. However, majority of them are either ineffective or last for a short period of time. It has been reported that lasers, particularly Neodymium- doped: Yttrium Aluminum Garnet laser (Nd: YAG), can be helpful in the treatme...
متن کاملHolmium: yttrium-aluminum-garnet (Ho:YAG) laser for resection of bladder tumor in a pediatric patient
Bladder tumours are rare in children, with only 0.4% of cases occurring in the first 2 decades of life. Herein, a pediatric patient who underwent TUR-B with a holmium: yttrium-aluminum-garnet (Ho:YAG) laser is presented. Its histopathology was reported as urothelial papilloma.
متن کاملThe Role of Factors Influencing the Optical Properties of Yttrium Aluminum Garnet Ceramic Body
Yttrium Aluminum Garnet (Y3Al5O12) is a transparent ceramic with a wide range of applications such as high mechanical strength windows, high power laser sources and radiation detectors. The most important challenge in making these ceramics is the problem of low light transmittance, especially in the visible area in the range of 400 to 700 nm, which is greatly affected and reduced by various fac...
متن کاملGas chromatographic and mass spectroscopic analysis of excimer and erbium: yttrium aluminum garnet laser-ablated human cornea.
The photoablative products from human cadaver corneas treated with lasers were investigated using gas chromatography and mass spectroscopy. The photoablations were done separately with an excimer laser (193 nm) and with an erbium: yttrium aluminum garnet (Er:YAG) laser (2.94 microns). More than 20 different types of molecules with a molecular weight of 40-400 mass units could be identified, mos...
