Beaming random lasers with soliton control

Article | OPEN | Published: 21 September 2018 Sreekanth Perumbilavil, Armando Piccardi, Raouf Barboza, Oleksandr Buchnev, Martti Kauranen, Giuseppe Strangi  Gaetano Assanto Random lasers are resonator-less light sources where feedback stems from recurrent scattering at the expense of spatial profile and directionality. Suitably-doped nematic liquid crystals can random lase when optically pumped near resonance(s); moreover, through molecular...

Researchers discover that nanometer-thick tin selenide crafted in thin films of connected ‘nanoflakes’ shows promise for thermoelectric energy conversion.

From the Journal:  Journal of Applied Physics By AIP News Staff WASHINGTON, D.C., March 27, 2018 -- Single crystal tin selenide (SnSe) is a semiconductor and an ideal thermoelectric material; it can directly convert waste heat to electrical energy or be used for cooling. When a group of researchers from Case Western...
