Abstract

We report a paratellurite (TeO2) Brillouin laser utilising an etalon as a dichroic input coupler in a three-mirror standing wave cavity. By adjustment of the cavity resonance conditions, the oscillator is switched between a multiply resonant mode of operation in which there is pump enhancement and the generation of cascaded Stokes orders, or a singly resonant mode in which only the first Stokes order is generated. In the multiply resonant mode, the generation of a Brillouin frequency comb spaced at 17.4 GHz and spanning 104 GHz was demonstrated. In the singly resonant mode, a factor of 4 reduction in linewidth was measured from the pump seed laser to the Brillouin laser output.
