Active subnanometer spectral control of a random laser
We demonstrate an experimental technique that allows to achieve a robust
control on the emission spectrum of a micro random laser and to select
individual modes with sub-nanometer resolution. The presented approach relies
on an optimization protocol of the spatial profile of the pump beam. Here we
demonstrate not only the possibility to increase the emission at a wavelength,
but also that we can isolate an individual peak suppressing unwanted
contributions form other modes
