A diode-pumped Yb:KYW femtosecond laser frequency comb with stabilized carrier-envelope offset frequency
Stephanie Meyer, J A. Squier, Scott A. Diddams
We describe the detection and stabilization of the carrier envelope offset (CEO) frequency of a diode-pumped Yb:KYW (ytterbium- doped potassium yttrium tungstate) fs-oscillator that is spectrally centered at 1033 nm. The system consists of a passively mode-locked femtosecond laser that produces 290 fs pulses at a repetition rate of 160 MHz. These pulses are first amplified, spectrally broadened and temporally compressed to 80 fs, and then launched into microstructured fiber to produce an octave-spanning spectrum. An f-2f nonlinear interferometer is employed with the broadened spectrum to detect and stabilize the CEO frequency through feedback to the pump laser current. These results demonstrate that such a Yb-doped tungstate can provide an efficient, compact, high-repetition-rate optical frequency comb with coverage from 650-1450 nm.
