Design of Scatterer Configuration for Spectral Optimization of Random Lasers

Not Accessible

Your library or personal account may give you access


The two-dimensional structure of a random gain medium was designed to obtain the specified emission spectrum from a random laser. Structural optimization was performed using a direct binary search method. The simulation results showed that the emitted light can be concentrated within one or more specific wavelength ranges. The effect of the fabrication errors on the optimized laser emission spectrum was also examined.
