Which risk increases significantly when coolant flow's Reynolds number exceeds channel limits inside a high-power disk laser?

A)Increased frequency doubling efficiency
B)Development of turbulent flow regime
C)Improved thermal lens compensation
D)Stable laminar flow establishment

💡 Explanation

A high Reynolds number indicates inertial forces dominate viscous forces; therefore, transition turbulence is the reason, introducing large pressure fluctuations and potential mixing problems in the cooling. Avoiding turbulent flow lowers this risk; rather than better laminar flow.
