Compact, temperature-stable multi-gigahertz passively modelocked semiconductor disk laser |
Measured and sech2 fitted autocorrelation trace (a) and RF spectrum (b) of the mode-locked pulses. The inset in panel (a) shows the optical spectrum and the inset in panel (b) shows the RF spectrum on a 5-GHz span. The radius of curvature of the OC is 100 mm. |
