Abstract:

We have measured the cooperative upconversion parameter in ErYAG using the z-scan technique as a function of Er concentration 0.5 to 5 with the sample at room temperature 298 K and 80 K. The value we obtain at room temperature is 2-3 times larger than previously reported. The value we obtain at 80 K is approximately eight times larger than the value at room temperature. One advantage of the z-scan technique is that the measurement can be carried out with the same quasi-cw diode laser that will pump the ErYAG laser being developed.
