| 摘 要： | In this paper the temperature-related performances of the Yb^3＋：YAG disc laser has been investigated based on quasi-three level rate equation model. A compact diamond window cooling scheme also has been demonstrated. In this cooling scheme, laser disc is placed between two thin discs of single crystal synthetic diamond, the heat transfer from Yb^3＋：YAG to the diamond, in the direction of the optical axis, and then rapidly conducted radically outward through the diamond to the cooling water at the circumference of the diamond/Yb^3＋ ：YAG assembly. Simulation results show that increasing the thickness of the diamond and the overlap-length （between diamond and water） decreases the disc temperature. Therefore a 0.3-0.5 mm thick diamond window with the overlap-length of 1.5 2.0 mm will provide acceptable cost effective cooling, e.g., with a pump intensity of 15 kW/cm^2 and repetitive rate of 10 Hz, to keep the maximum temperature of the lasing disc below a reasonable value （310K）, the heat exchange coefficient of water should be about 3000 W/m^2K.

| Abstract: | In this paper the temperature-related performances of the Yb3+:YAG disc laser
has been investigated based on quasi-three level rate equation model. A compact
diamond window cooling scheme also has been demonstrated. In this cooling scheme,
laser disc is placed between two thin discs of single crystal synthetic diamond, the
heat transfer from Yb3+:YAG to the diamond, in the direction of the optical
axis, and then rapidly conducted radically outward through the diamond to the
cooling water at the circumference of the diamond/Yb3+:YAG assembly.
Simulation results show that increasing the thickness of the diamond and the
overlap-length (between diamond and water) decreases the disc temperature. Therefore
a 0.3--0.5mm thick diamond window with the overlap-length of 1.5--2.0mm will
provide acceptable cost effective cooling, e.g., with a pump intensity of
15kW/cm2 and repetitive rate of 10Hz, to keep the maximum temperature of the
lasing disc below a reasonable value (310K), the heat exchange coefficient of water
should be about 3000 W/m2K. |
