In this Work, Laser energy effects on optical and morphological properties of TiO2 thin film has been carried out using Reactive Pulsed Laser as a Deposition technique (RPLD). Q-switched Nd-YAG laser with (λ=1.06μm, t =7nsec) and different energies have been used to ablate pure Titanium target and deposited thin films on glass substrates with constant substrate temperature of (343K). The optica...

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...

introduction: trichophyton rubrum is one of the most common species of dermatophytes which affects superficial keratinous tissue. it is not especially virulent but it can be responsible for considerable morbidity. although there are different therapeutic modalities to treat fungal infections, clinicians are searching for alternative treatment because of the various side effects of the present t...

dentin hypersensitivity (dh) is a relatively common painful condition among dental problems. although many studies have been performed regarding the diagnosis and treatment of dh, dental practitioners are still confused about the definite diagnosis and treatment.the use of lasers as a treatment for dentin hypersensitivity was first introduced in 1985. laser treatment in dentin hypersensitivity ...

citric acid and tetracycline hcl are the most common clinical root demineralization agents used in periodontal practice. in this comparative in vitro study the effects of nd: yag laser radiation on root surface was compared to that of citric acid and tetracycline hcl using sem. a total of twenty-one freshly extracted periodontally diseased single rooted premolar teeth were root planned in vitro...

Background and Objective. There has been a heightened interest in laser-assisted fat reduction procedures. We aimed to determine if lipolysis with the 1,320 nm Nd-YAG short-pulsed laser without subsequent suction results in satisfactory contouring of the upper extremity. Materials and Methods. Unilateral laser lipolysis of the upper arm was performed on 5 patients. Subcutaneous, subdermal, and ...

Intratracheal combustion of a fiberoptic bronchoscope and an endotracheal tube occurred during the treatment of severe tracheal stenosis with the neodymium-YAG laser. This recognized hazard of CO2 laser surgery has not been reported previously with the use of the Nd-YAG laser. Fire hazard is inevitable when a laser is used in the airway, but the risk can be diminished. Rapid removal of the burn...

In the present research work we present the optical emission studies of the Indium (In) – Tin (Sn) plasma produced by the first (1064 nm) harmonic of an Nd: YAG nanosecond pulsed laser. The experimentally observed line profiles of neutral Indium (In I) and Tin (SnI) are used to extract the electron temperature (Te) using the Boltzmann plot method. Whereas, the electron number density (Ne) has b...
