Abstract
We present a dual-focus second harmonic generation (SHG) microscopy approach based on stable, compact, and inexpensive fiber technology. One-tenth of the fiber laser output is coupled into a 100 m (=500 ns) long single-mode fiber and further amplified to achieve two separately guided beams with time-alternating pulse trains. SHG detection is performed sequentially, generating two individual images in one scan. Thus, the configuration allows for imaging of distinct areas within the field of view at twice the repetition rate of the fiber laser but is readily extended to a multiple of the repetition rate with tens of foci.
