Evaluation of a laser diode array as an efficient approach to laser weeding

Weed Technology
In-crop site-specific weed recognition systems have enabled precise and selective use of alternative nonchemical weed control technologies to provide much-needed support for weed management programs in large-scale cropping systems. Laser weeding has long

Novel light therapies in treatment of onychomycosis

Przegląd Dermatologiczny, 2016
Onychomycosis is a frequent nail disease. Standard treatment is not sufficient in some patients. The aim of the study is to provide an overview of laser, UVC and photodynamic therapy of onychomycosis. The use of Nd:YAG laser is described in many articles,

Selective laser ablation of carious lesions using simultaneous scanned near-IR diode and CO₂ lasers [PDF]

SPIE Proceedings, 2017
Previous studies have established that carious lesions can be imaged with high contrast using near-IR wavelengths coincident with high water absorption, namely 1450-nm, without the interference of stains. It has been demonstrated that computer-controlled laser scanning systems utilizing IR lasers operating at high pulse repetition rates can be used for

Augmentation of the mechanical and chemical resistance characteristics of an Al2O3-based refractory by means of high power diode laser surface treatment [PDF]

, 2003
Augmentation of the wear rate and wear life characteristics of an Al2O3-based refractory within both normal and corrosive (NaOH and HNO3) environmental conditions was effected by means of high power diode laser (HPDL) surface treatment.

\u2022\tVolcanic CO2 flux measurements by Tunable Diode Laser absorption Spectroscopy

Proc GOLDSCHMIDT CONFERENCE, Gold2013:abs:5563, 2013
Introduction In the last decades, the use of near-infrared room-temperature diode lasers for gas sensing has grown significantly. The use of these devices, for instance in combination with optical fibers, is particularly convenient for volcanic monitoring applications [1,2].

Folliculotropic mycosis fungoides of the face successfully treated combining CO2 laser and conventional photodynamic therapy (c-PDT)

Photodiagnosis and Photodynamic Therapy
A 57-year-old male with a three-year history of folliculotropic mycosis fungoides (FMF), previously treated systemically, received CO2 laser-assisted photodynamic therapy (PDT) following the recurrence of FMF on the face.

Photoresponse of Metal-PbTe Structures to CO2 Laser Excitation

Medžiagotyra, 2014
We report on the investigation of photoresponse signal arising across metal-PbTe structures exposed to CO2 laser radiation. Three different metals, Al, Au, and Bi, have been used for Schottky diode-like structure fabrication.
