Nonlinear propagation of intense femtosecond laser pulses in bulk transparent media leads
to a specific propagation regime, termed femtosecond filamentation, which in turn produces …

Enabling broad tunability, high peak and average power, ultrashort pulse duration, and all
known modes of laser operation-transition-metal (TM)-doped II-VI chalcogenides are the …

Polycrystalline ZnSe is an exciting source of broadband supercontinuum and high-harmonic
generation via random quasi phase matching, exhibiting broad transparency in the mid …

We demonstrate incoherent broadband cavity enhanced absorption spectroscopy in the mid-
