Single crystal monolithic up-converter solar cell device tandems with integrated optics
Georgios E. Arnaoutakis, Elena Favilla, Mauro Tonelli +1
Solar photons possessing energy less than the band-gap of a single-junction solar cell can be utilized via the up-conversion (UC) of two or more photons, resulting in the emission…
Tm-doped Crystals for mid-IR Optical Cryocoolers and Radiation Balanced Lasers
Saeid Rostami, Alexander R. Albrecht, Azzurra Volpi +3
We report the complete characterization of various cooling grade Tm-doped crystals including the first demonstration of optical refrigeration in Tm:YLF crystals. Room temperature l…
Yellow laser performance of Dy in co-doped Dy,Tb:LiLuF
Giacomo Bolognesi, Daniela Parisi, Davide Calonico +6
We present laser results obtained from a Dy-Tb co-doped LiLuF crystal, pumped by a blue emitting InGaN laser diode, aiming for the generation of a compact 578 n…
Diode-pumped Pr:BaY2F8 cw orange laser
Davis Pabœuf, Oussama Mhibik, Fabien Bretenaker +3
We report the realization of the continuous wave laser emission in the orange at 607 nm from a Pr:BaY2F8 (Pr:BYF) crystal pumped by a blue GaN laser diode. A maximal output power o…
