© 2019 Astro Ltd. Four-wave mixing (FWM) of ultrashort laser pulses in a highly nonlinear photonic-crystal fiber is shown to provide a multimodal source of broadband quantum states of light. In the regime of low pump powers, ...

Temporal shape of a primary photon echo (PPE) in a ruby is experimentally investiagted. Using of special equipment, including a dye laser and a stroboscopic oscilloscope, allows to observe the "beats" of temporal shape of ...
