High-performance laser power converts for direct-energy applications
Optics Express, 2022 Six-junction GaAs laser power converts (LPCs) were designed and fabricated. Each subcell is vertically connected by p++-AlGaAs: C/n++-AlGaAs: Si: Te (1:2) tunnel junction with good thermal stability and a record peak tunneling current density of 1867 A/cm2. The I-V characteristics of LPCs with an aperture of 10×10 mm2 were investigated as a function of

High-power non linear frequency converted laser diodes [PDF]
SPIE Proceedings, 2015 We present different methods of generating light in the blue-green spectral range by nonlinear frequency conversion of tapered diode lasers achieving state-of-the-art power levels. In the blue spectral range, we show results using single-pass second harmonic generation (SHG) as well as cavity enhanced sum frequency generation (SFG) with watt-level ...

High power diode lasers converted to the visible [PDF]
2017 IEEE High Power Diode Lasers and Systems Conference (HPD), 2017 High power diode lasers have in recent years become available in many wavelength regions. However, some spectral regions are not well covered. In particular, the visible spectral range is lacking high power diode lasers with good spatial quality. In this paper, we highlight some of our recent results in nonlinear frequency conversion of high power near
