In this paper, we discussed a method of controling the working temperature of the diode pumped solid laser crystal. At present, we explores a new kind of heat sink--microchannel heat sink. In order to the heat dissipation of the diode pumped solid laser crystal, and its cylindrical shape, we applied the heat theory of microchannel to laser crystal, and designed a microchannel structure of solid state laser cooler-- a combination of fan-shaped jet microchannels solid laser cooling structure.
The microchannel is designed in these conditions,such as: the interior spatial distribution of crystal、pump sources are used by Gaussian distribution、pump power for 10w、the crystals of Nd:YAG、the outside of the crystal was connected with the microchannel heat sink in this paper,and the temperature of all the connect points which are distributed on the outside of the crystal and the interior of the heat sink are equal、and the whole surface are not,etc.For end face pump laser, its side are used as cooling. For improving the quality of beam, you can decrease the radius, mean while can cause high heat dissipation in such a small area. Hence, the research of high heat dissipation density are studied. In this structure, the smaller surface of the crystal means the smaller contact points of the heat sink of the microchannel. But realizing an effective cooling by using a microchannel in such a small contact point is realy a technical problem. An appropriate structure of microchannel which realized the dissipation in a small area is come up in this paper.
This design can avoid the brust problem of the crystal because of the overtop temperature while welding. Meanwhile, the heat sink of the microchannel can also take the most heat of the laser crystal. Theoretical analysis shows that the device which can effectively realize the dissipation, reduce the difficulty of the workmanship, and improve the control efficiency of the laser crystal's temperature. |
