Selective transverse mode operation of an all-fiber laser with a mode-selective fiber Bragg grating pair.
TL;DR: This work has implemented a ytterbium-doped all-fiber laser operating in the second-order (LP11) transverse mode, and it is shown that this approach has great scalability and can be applied to other working modes and spectral regimes.

Mid-infrared coincidence measurements on twin photons at room temperature
Mattia Mancinelli,Alessandro Trenti,Sara Piccione,Giorgio Fontana,Jeppe Seidelin Dam,Peter Tidemand-Lichtenberg,Christian Pedersen,Lorenzo Pavesi +7 more
TL;DR: The way to quantum measurements in the MIR is paved by the demonstration of a room temperature coincidence measurement with non-degenerate twin photons at about 3.1 μm by means of efficient up-converter modules.

Mesoscale engineering of photonic glass for tunable luminescence
Yongze Yu,Zaijin Fang,Chuansheng Ma,Hiroyuki Inoue,Guang Yang,Shupei Zheng,Danping Chen,Zhongmin Yang,Atsunobu Masuno,Jiri Orava,Jiri Orava,Shifeng Zhou,Jianrong Qiu +12 more
TL;DR: In this paper, Zhou et al. proposed a mesoscale engineering approach to manage dopant-dopant and host interaction by manipulation of mesoscales in a single active material, which results in dramatically inhomogeneous broadening of dopant and flattening of the spectral shape in glass and fiber.

Optical Constants of Water in the 200-nm to 200-microm Wavelength Region.
George M. Hale,Marvin R. Querry +1 more
TL;DR: Extinction coefficients k(lambda) for water at 25 degrees C were determined through a broad spectral region by manually smoothing a point by point graph of k( lambda) vs wavelength lambda that was plotted for data obtained from a review of the scientific literature on the optical constants of water.

Quantum cascade laser
TL;DR: In this paper, the authors proposed a quantum cascade laser consisting of a gain region (14) consisting of several layers (20) each including: alternating strata of a first type (28) defining each AllnAs quantum barrier and strata with injection barriers interposed between two of the layers.

Laser beam combining for high-power, high-radiance sources
TL;DR: In this paper, the authors provide an overview of beam combining and highlight some of the tradeoffs among beam-combining techniques, including wavelength (spectral) and coherent (phased array) techniques.
