Long-wavelength laser power converters for optical fibers

Conference Record of the Twenty Sixth IEEE Photovoltaic Specialists Conference - 1997, 2002
Measured responsivity and illuminated I-V data are presented for III-V In/sub x/Ga/sub 1-x/As-based photovoltaic cells with bandgaps of 1.42 eV (GaAs), 0.74 (lattice-matched In/sub 0.53/Ga/sub 0.47/As), and 0.55 eV ("extended" lattice-mismatched In/sub 0.7/Ga/sub 0.3/As) relevant to their application as laser power converters (LPCs) sensitive to ...

Laser Power Multiplication in a Parametric Frequency Converter with a Cavity Dumper

Japanese Journal of Applied Physics, 1981
It is shown theoretically that by using a parametric frequency converter with a cavity dumper, power enhanced laser pulses of moderately compressed pulse-duration, shorter wavelength and broader bandwidth can be obtained efficiently from relatively long fundamentals, resulting in useful laser-fusion driver pulses.

Laser (λ = 809 nm) power converter based on GaAs

Semiconductors, 2017
Laser-power converters with a wavelength of λ = 809 nm are fabricated on the basis of single-junction AlGaAs/GaAs heterostructures grown by the method of liquid-phase epitaxy (LPE). Photovoltaic modules with an operating voltage of 4 V for converting radiation of various densities are developed and tested.

Passive Switch-Mode Voltage-to-Power Converters in Laser Systems

2017
Some applications require a stabilized laser beam power. For this purpose, many low-power LDs have a photodiode attached to the rear facet. Light penetrates the rear facet mirror and is converted by the photodiode into a signal proportional to the laser beam power.
