A compact energy transducer for power generation from respiration
(Journal of Microelectromechanical Systems, 2019)
This paper reports a compact magnetic transducer developed for generating electrical power from respiration. The device incorporates a side-drive turbine rotor with embedded permanent magnets and two stators, integrated ...
Temperature dependence of the emission cross-section and fluorescence lifetime in Cr:LiCAF, Cr:LiSAF, and Cr:LiSGaF between 78 K and 618 K
(2023)
Cr:Colquiriites (Cr:LiCAF, Cr:LiSAF, and Cr:LiSGaF) are well-known for their broad emission bands in the near-infrared region. Unfortunately, due to their relatively weak thermomechanical strength, average powers from ...
Broadly tunable two-color lasing of Cr:LiCAF with on-surface and off-surface optical axis birefringent filters: performance comparison
(Applied Optics, 2022)
We studied the two-color lasing performance of a Cr:LiCAF laser using crystal quartz on-surface and off-surface optical axis birefringent filters (BRFs). Four different on-surface optical axis BRFs with thicknesses of 2 ...
