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.
