FIG. 1.

(Color online) (a) Schematic illustration of the experimental setup. BS, OC, and HR are the beam-splitter, output coupler, and high-reflective mirror, respectively. (b) Exemplary streak-camera images of the laser intensity as function of the emission wavelength and time for the intra-cavity power of 6 W (left) and 390 W (right). The camera is operated in the single-sweep mode with the temporal window set to 200 μs. Corresponding time-averaged spectra of the laser emission are shown in the respective insets.

FIG. 2.

(Color online) Relative probabilities for the relative difference ΔI12 = (I1 − I2)/(I1 + I2) of the intensities I1 and I2 of the dual-color emission are plotted in (a1), (b1), and (c1) for the intra-cavity power of 6 W, 110 W, and 390 W, respectively. Corresponding correlation diagrams of the intensity of the first color as function of the intensity of the second color are shown in (a2), (b2), and (c2). The intensities are normalized to the respective average values . The (I1 = I2) curve is shown by the dotted line in each plot for comparison.

Image of FIG. 3.
FIG. 3.

(Color online) (a) Intra-cavity power as function of the effective pump power with the solid line as guide to the eye. (b) The interval of twice the standard deviation σ of the respective intensity difference ΔI12 distribution of the two-color emission. (c) Correlation coefficient for the simultaneously measured intensities at the two laser wavelengths.
