We present the single-slit diffraction of the arbitrary vector fields with different parameters m, n, and f0 theoretically and experimentally. The single slit covers the polarization singularity in the center and therefore the influence of the polarizatio
A diode-side-pumped Tm,Ho:LuLiF laser at 2-1m wavelength obtained in a ring resonator and its amplification experiment are reported. At the maximum pump energy of 4.7 J available for the oscillator, the output energy per pulse for the oscillator decreases
An ultra-broadband and fabrication-tolerant silicon polarization rotator splitter is proposed in this Letter. Benefitting from the broadband and low-loss characteristics of the bi-level taper and counter-tapered coupler, the designed device has a simulate
