Medium-power diode-pumped Nd:BaY2F8 laser
Optics Express, 2003 We report what is to our knowledge the first Nd:BaY2F8 (Nd:BaYF) laser pumped with a multiwatt fiber-coupled diode array tuned at approximately 804 nm. As much as 2.4 W were obtained with 6.2 W of absorbed pump power, showing efficient operation (51% slope efficiency), excellent beam quality (M2=1.1), and weak thermal lensing. Small intracavity losses (

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum
Advanced Materials, EarlyView.Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

Transient Analysis of Pump-induced Lensing Effects in Alexandrite Lasers Using Pump-Probe Technique [PDF]
EPJ Web of ConferencesA novel transient pump-probe method is used to differentiate thermal and population pump-induced lensing mechanisms. In diode-pumped Alexandrite lasers, excellent agreement is found between theory and experiment and the population lens is found to be ...

DIODE PUMPED 2- μm Holmium Laser
Advanced Solid State Lasers, 1986 A high efficiency laser diode array pumped Nd:YAG solid state laser has recently been demonstrated.1 We report for the first time a diode array pumped rare-earth laser other than Nd. Laser action was observed on the trivalent Holmium 5I7→5I8, 2.1 μm transition. Laser sources in this wavelength region are required in infrared optical fiber communication

Advanced Materials Interfaces, EarlyView.We report electrochemical quantum capacitance spectroscopy as an ambient, in situ probe for defect‐mediated electronic structure at 2D material interfaces. Using monolayer MoS2, the method resolves band edges and vacancy states, tracks sulfur‐vacancy evolution during hydrogen evolution, and links interfacial density‐of‐states changes to nearly ...

Advanced Materials Technologies, EarlyView.Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.
