The development of the first Yb3+ doped microchip and waveguide laser in germanate glass (GPGN) is reported with a composition of 54GeO2-31PbO-4Ga2O3-9Na2CO3-1.5Yb2O3 (Yb3+: GPGN). Up to 51mW at 650mW of input power is obtained from a L=4.5mm long cavity microchip laser operating at 1052nm with slope efficiency of ~30% and laser threshold of ~230mW. Single track (type 1) waveguides are inscribed 150μm beneath the surface of the sample in the femtosecond laser cumulative heating regime. Pulse energies range from15nJ to 75nJ producing guiding structures ranging from d= 12μm to 60μm. Waveguide laser operation is achieved for a 24μm diameter waveguide with up to ~20mW output power generated at 1.07μm for 650mW of 976 nm pump power.
