【Abstract】 This paper analyzes the thermal characteristics of tube laser crystal in different cooling conditions. The relations of stress limit to relative thickness of tube are obtained. The relations show that the proper selection of thickness and cooling condi-tions can make the damage limit much higher than red crystals.更多还原
