We present a novel Yb:KGd(WO 4 ) 2 oscillator design that generates six beams of temporally delayed, 253 fs, 11 nJ pulses. This allows multifocal nonlinear microscopy to be performed without the need for complicated optical multiplexers. We demonstrate our design with twelve simultaneously acquired two-photon, second-harmonic and/or thirdharmonic images generated from six laterally separated foci.
