We report a 1.5-GHz Kerr-lens-modelocked (KLM) Yb:Y2O3 ring laser, constructed by directly bonding the cavity components onto an aluminum baseplate. Stable unidirectional operation with an output power ≥ 10 mW was obtained for pump-diode currents of 300–500 mA, corresponding to a total electrical power consumption of 1.5 W. After repetition-rate stabilization, a comparison with a conventionally-constructed identical laser showed a 50% reduction in phase noise. In free-running operation
the bonded laser showed superior passive repetition-rate stability. The bonding process follows an already proven integration approach in space-borne instrumentation, mapping a development pathway for KLM lasers in aerospace applications.
