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
