WGM Microrod Laser Fabricated by pulsed CO2 Laser Micromilling
Introduction Whispering Gallery Mode (WGM) microlasers have been of a great interest owing to their low threshold and narrow linewidth lasing due to their high Q and small mode volume. Most of the fabrication methods [1-3] are non-controllable and non-reproducible which rely on fiber-tip melting, such as microspheres [3, 4] or splicing of small active-fiber stubs [3]. Microresonators are realiz...
متن کاملLaser Rock Drilling by A Super-Pulsed CO2 Laser Beam
High power carbon dioxide lasers have successfully been used in drilling or cutting ngineering materials such as metals, polymers and ceramics over the years. Can a arbon dioxide laser be used to efficiently drill different rocks in a deep gas well? esearch sponsored by US Department of Energy has been carried out to answer this uestion. This paper will report the study results of using a super...
متن کاملPredicting gas decomposition in an industrialised pulsed CO2 laser
A model is developed for the breakdown and regeneration of component gases in an industrialised TEA CO2 laser, both with and without internal catalysts, and is found to be in excellent agreement with experimental data. The laser was found to be stable at 02 levels in excess of 2%, whereas previously reported values suggest stable operation at values of less than 1%. This is thought to be relate...
متن کاملTreatment of scars after aesthetic surgery utilizing of a combination of pulsed dye laser and fractional CO2 laser
Background and Aim: Undesirable appearance of the scar tissue after aesthetic surgery can affect the outcomes and patient satisfaction. In recent years, early laser therapy had been encouraged to reduce the scar tissue formation. However, the available evidence regarding the outcomes of laser therapy utilizing combined lasers are limited. In the current study, the effects of combined laser ther...
متن کاملMeasurement of a 3D Ultrasonic Wavefield Using Pulsed Laser Holographic Microscopy for Ultrasonic Nondestructive Evaluation
In ultrasonic array imaging, 3D ultrasonic wavefields are normally recorded by an ultrasonic piezo array transducer. Its performance is limited by the configuration and size of the array transducer. In this paper, a method based on digital holographic interferometry is proposed to record the 3D ultrasonic wavefields instead of the array transducer, and the measurement system consisting of a pul...
