Performance of the SASE amplifier of the TEU-FEL project [PDF]

open access: yes, 1991
The free-electron laser of the TEU-FEL project of the University of Twente will be driven by a photoinjector followed by a racetrack microtron. The injector, which is now under construction, will provide a very high-brightness electron beam with an ...

Macular laser photocoagulation in the management of diabetic macular edema: Still relevant in 2020?

open access: yesTaiwan Journal of Ophthalmology, 2020
Macular laser photocoagulation (MLP) is inferior to intravitreal vascular endothelial growth factor (VEGF) inhibitors in the treatment of center-involved diabetic macular edema (DME).

Micropulse diode laser trabeculoplasty – 180‐degree treatment [PDF]

open access: yesActa Ophthalmologica, 2010
Abstract.Purpose:  To evaluate the outcome of 180° micropulse diode laser trabeculoplasty (MDLT) in patients with open‐angle glaucoma.Methods:  A retrospective review of 40 eyes of 29 MDLT‐treated patients with a minimum follow‐up time of 6 months. Successful outcome was defined as follows: (i) a ≥20% or (ii) a ≥3‐mmHg decrease of intraocular pressure (

Advantages of Micropulse Technology as a Method of Choice for the Treatment of Secondary Glaucoma in Patients with Corneal Diseases

open access: yesOftalʹmologiâ, 2022
Postkeratoplasty glaucoma develops after cornea transplantation in 10–53 % cases. For ophthalmotonus stabilization in patients, it was proposed to use micropulse laser surgery.Purpose. To evaluate the effectiveness of micropulse laser surgery in patients

High frequency pressure oscillator for microcryocoolers [PDF]

open access: yes, 2008
Microminiature pulse tube cryocoolers should operate at a frequency of an order higher than the conventional macro ones because the pulse tube cryocooler operating frequency scales inversely with the square of the pulse tube diameter.

Photoionization experiments with the ultrafast EUV laser 'FLASH' - free electron laser in Hamburg [PDF]

open access: yes, 2007
The advent of mirror-less Free Electron Lasers emitting polarised and coherent 'laser-like' beams of high peak (> 1GW) and average (up to 100mW) powers in the extreme-UV (EUV) and X-ray bands of the electromagnetic spectrum heralds a new era in the study

Yellow Pattern 577-nm Micropulse Laser: Treatment of Macular Edema from Radiation Retinopathy – A Case Report

open access: yesCase Reports in Ophthalmology, 2017
We report a case of a 60-year-old Asian male who developed radiation retinopathy 23 years after initial radiotherapy for nasopharyngeal carcinoma and was successfully treated with yellow pattern 577-nm micropulse laser. Secondary macular edema and visual
