AIMS To compare the refractive error 1 to 3 years after cryotherapy or diode laser treatment for threshold retinopathy of prematurity. METHODS Twenty six infants treated with diode laser and 17 infants treated with cryotherapy underwent cycloplegic refraction during follow up. RESULTS After 3 years of follow up, 94.1% of patients had myopia (right eye if bilateral) following cryotherapy and...

We report on methods for widening modulation bandwidths of commercial laser diode drivers Inexpensive commercial laser diode drivers have many important characteristics but unfortunately their modulation bandwidths are often restricted to below kHz Here techniques involving p channel and n channel JFETs have been tested to enhance the modulation bandwidth of drivers suitable for common laser an...

BACKGROUND Since its appearance in the dental area, the laser has become a treatment of choice in the removal of lesions in the oral soft tissues, due to the numerous advantages they offer, being one of the most used currently the diode laser. The aim of this review was to determine the efficacy and predictability of diode laser as a treatment of soft tissue injuries compared to other surgical ...

Laser welding with CO2, fiber and various types of solidstate lasers is a well established process currently utilized in a wide range of industries and applications. However, recent technological developments in high power diode laser technology have expanded the capabilities of laser welding, as well as changed its cost characteristics. As a result, diode lasers are poised to replace tradition...

In this paper we discuss how different feedback gratings affect the tuning range and the output power of external feedback diode laser systems. A tunable high-power narrow-spectrum external-cavity diode laser system around 455 nm is investigated. The laser system is based on a high-power GaN diode laser in a Littrow external-cavity. Both a holographic diffraction grating and a ruled diffraction...

Ž. (2014) Laparoscopic partial nephrectomy with diode laser: a promising technique. Photomedicine and Laser Surgery, 32 (2). pp. 5 Abstract Objective: Aim of this study was to evaluate application of diode laser in laparoscopic partial nephrectomy (LPN) and to question this technique in terms of ease of tumor excision and reduction of warm ischaemia time (WIT).

INTRODUCTION Laser dentistry is a one of the upcoming advanced treatment modality for oral mucosal lesions. Diode laser is a soft tissue laser that has found much acceptance in all branches of dentistry. Available compact size and feasibility has render diode laser an enhanced tool for today's clinical practice. The aim of this study is to determine the efficacy and safety of diode laser for th...

BACKGROUND The aim of the present study was to compare the effects of Er:YAG and diode laser treatments of the root surface on intrapulpal temperature after scaling and root planing with hand instruments. METHODS Fifteen extracted single-rooted teeth were scaled and root planed with hand instruments. The teeth were divided into 3 groups of 5 each and irradiated on their buccal and lingual sur...

Excessive gingival pigmentation is a major aesthetic concern in modern society, though it is not a medical problem they consider it as a negative attribute. Patients with gingival hyperpigmentation usually complain and request cosmetic therapy, particularly if the pigmentation is visible during speaking and smiling. Various depigmentation methods, including burr abrasion, cryosurgery, electro-s...
