Hydrodynamic and thermal simulation for high energy large size Nd:YAG liquid-cooled laser amplifier

Modeling and Measurement of Thermal Effect in a Flashlamp-Pumped Direct-Liquid-Cooled Split-Disk Nd:LuAG Ceramic Laser Amplifier

“…The thickness of the cooling fluid directly determines the heat dissipation effect of the gain medium. The heat dissipation capacity is generally expressed by the convective heat transfer coefficient, which is defined as [17], ( ) In the fluid channel design, the choice of the thickness of the cooling fluid is particularly critical. The thickness of the cooling fluid directly determines the heat dissipation effect of the gain medium.…”

“…The thickness of the cooling fluid directly determines the heat dissipation effect of the gain medium. The heat dissipation capacity is generally expressed by the convective heat transfer coefficient, which is defined as [17], Figure 17 shows that the heat transfer coefficient increases with fluid velocity and decreases with thickness. The thickness of cooling fluid introduced in Section 2.1 is 2 mm and the upper limit of the cooling flow rate is 6 L/min.…”
