Figures

Image of FIG. 1.
FIG. 1.

(Color online) Reflection (solid curve) normal to the surface and PL spectrum (dashed curve) measured to the cleaved edge of the chip. The dotted vertical lines denote the maximum of PL and cavity dip position, respectively. The arrows indicate the different wavelength shift rates with rising temperature of PL and cavity dip. The dash-dotted lines mark the end of the stop band which is given by the first minima besides the high reflective band.

(Color online) UV tuning curves for different heatsink temperatures T HS = +10 °C (triangles), T HS = −10 °C (stars), and T HS = −25 °C (filled circles) at a constant pump power of P p = 5.85 W and a typical spectrum of the UV laser emission (solid curve) for T HS = −25 °C with a UV output power of P UV = 67 mW.

(Color online) Power transfer curve (filled circles) at heatsink temperature T HS = −25 °C with a parabola fit (solid curve) and UV tuning curve (stars) for a heatsink temperature T HS = −27 °C at elevated pump power of P p = 6.92 W. Inset: typical beam profile.
