(a) False-color plot mapping how the − 20 dB spectral bandwidth of the laser output varies as a function of waveplate angles \(\theta _3\) and \(\theta _4\) with pump power at 195 mW. (b) An expanded view over the region indicated by the white square in (a) to illustrate the rarity of operating states of bandwidths exceeding \(\sim\) 100 nm (corresponding to red regions in the plot).
