Abstract

We present the design and development of a diode-pumped high average power femtosecond laser based on a crystal of Yb-ion doped potassium gadolinium tungstate (Yb:KGW) and a semiconductor saturable absorber for passive mode-locking. The laser delivered up to 0.85 W of average power with ~200 fs pulses at a repetition rate of 14.6 MHz, corresponding to a pulse energy of 60 nJ with a peak power of ~300 kW. The developed laser system was used to visualize the structure of muscle cells from Drosophila melanogaster larvae in vivo by acquiring high-resolution images with a nonlinear multimodal scanning microscope, capable of simultaneous detection of two-photon fluorescence, second and third harmonic signals.
