Optimal laser wavelength for efficient laser power converter operation over temperature

Applied Physics Letters, 2016
A temperature dependent modeling study is conducted on a GaAs laser power converter to identify the optimal incident laser wavelength for optical power transmission. Furthermore, the respective temperature dependent maximal conversion efficiencies in the radiative limit as well as in a practically achievable limit are presented.

Laser Power Converter Modules with a Wavelength of 809–850 nm

Technical Physics, 2020
We consider a high-efficiency photovoltaic module optimized for conversion of monochromatic radiation with a wavelength of 809–850 nm. The module includes four photovoltaic converters with a total area of 16 cm2, which operate with laser radiation of a power higher than 1 W and ensure a working voltage higher than 4 V.

Application of Series Resonant Converters in Laser Power Supply

2010 International Conference on Electrical and Control Engineering, 2010
The series resonant converter is a kind of DC to DC converter. The paper introduces the principle of the half bridge series resonant converter and the application of the half bridge series resonant converter in laser power supply. The series resonant converter has the high converting frequency and its output waveform comes near to the sine wave.

Photovoltaic laser-power converter based on AlGaAs/GaAs heterostructures

Semiconductors, 2016
Photovoltaic laser-power converters for a wavelength of λ = 809 nm are developed and fabricated on the basis of single-junction AlGaAs/GaAs structures grown by metal-organic vapor-phase epitaxy. The parameters of the photovoltaic structure constituted by an optical “window” and a cladding layer are optimized by mathematical simulation.
