A unified theory to construct exact optical rogue wave solutions of (1 1)-dimensional nonlinear Schrodinger equation with varying coefficients is proposed. The dynamics of the first-order optical rogue waves in nonlinear graded-index waveguide amplifiers
We present a continuously tunable Alexandrite laser. By means of chromatic dispersion prisms, the output spectrum in the range of 725-781 nm has been obtained. The output energy at the center wavelength of 750 nm has achieved 1 J per pulse. To obtain the
This Letter presents an optical design method based on the Seidel aberration theory for dynamic refocus systems. The function of a dynamic refocus system is to increase the amount of return photons when a pulsed laser travels over an extended height range
