Purpose: In the present work was made the comparative analysis in time domain and frequency domain to the acoustical pressure generate by the electric arc to determinate which of the two analysis meth...
Random laser emission from a surface-corrugated waveguide
Random laser emission surface-corrugated waveguide
2007/2/14
Here we report the random laser emission from surface corrugated waveguides. Discrete lasing modes, supernarrow spectral linewidth, and the existence of lasing threshold behavior have been observed. S...
