Evaluation of temperature rise following the application of diode and ErCr:Ysgg lasers: an ex vivo study

European Oral Research, 2018
Purpose Erbium, chromium: yttrium, scandium, gallium, garnet (ErCr:Ysgg) lasers have been frequently used in oral surgical procedures and are almost seen as alternatives to diode lasers. The aim of this comparative study was to analyze in an animal model

Management of Homogeneous Oral Leukoplakia by Diode Laser and Conventional Blade: A Randomized Controlled Trial

Journal of Indian Academy of Oral Medicine and Radiology
Background: Oral leukoplakia is a commonly seen pre-malignant lesion that appears as a white patch anywhere on the oral mucosa. Prevalence rate varies from 0.5% and 3.4% and malignant transformation ranges from 0.17% to 17.5% with a recurrence rate for ...

Use of diffuse reflections in tunable diode laser absorption spectroscopy: implications of laser speckle for gas absorption measurements [PDF]

, 2008
We report the effects of self-mixing interference on gas detection using tunable diode laser spectroscopy. For very weak feedback, the laser diode output intensity gains a sinusoidal modulation analogous to that caused by low finesse etalons in the ...

Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

Advanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Micropulse Laser in Glaucoma

Delhi Journal of Ophthalmology, 2019
A new type of diode laser-Cyclo G6 or the micropulse laser is helpful in reducing the intraocular pressure in glaucoma. It is a 810 diode laser from Iridex Corporation similar to the trans-scleral cyclophotocoagulation (TSCPC) laser but with a difference.

Passively mode-locked diode-pumped surface-emitting semiconductor laser

, 2000
A surface-emitting semiconductor laser has been passively mode locked in an external cavity incorporating a semiconductor saturable absorber mirror. The gain medium consists of a stack of 12 InGaAs-GaAs strained quantum wells, grown above a Bragg mirror ...

Tuning the Optoelectronic Properties of Wide Bandgap Perovskites: Data‐Driven Insights from Combinatorial Synthesis and High‐Throughput Experimentation

Advanced Functional Materials, EarlyView.
Combinatorial vapor deposition enables independent tuning of Cs/Pb and Br/Cl in wide‐bandgap perovskites. Automated multimodal mapping of 500+ compositions reveals a high‐energy optical transition that correlates with enhanced photoluminescence, defining a practical Cs/Pb window.
