Active volume scaling of gold vapor laser oscillating in ultraviolet and deep ultraviolet spectral ranges

open access: yesScientific Reports
Using six laser tubes with various diameters, lengths, and volumes of the active zone, an investigation on an ultraviolet gold vapor laser is undertaken. We achieve a maximal average output power of 1.07 W at 312.2 nm wavelength.

Systematic survey of pulsed laser deposition of YBa2Cu3O7 superconductor films on metal tapes

open access: yesScientific Reports
Pulsed laser deposition (PLD) of biaxially oriented cuprate superconducting films rapidly progresses from versatile research method to large scale production method. This development is likely the first example when PLD gets to industrial production tool.

Laser Active Optical Systems (LAOSs) for Material Processing

open access: yesMicromachines
The output energy of Laser Active Optical Systems (LAOSs), in which image brightness is amplified within the laser-active medium, is always higher than the input energy. This contrasts with conventional optical systems (OSs).
