Question 1

What are the structural advantages of a multi-module 20kW system over single-module setups?

Accepted Answer

A multi-module system divides the massive 20,000-Watt power requirement across several optimized laser sub-modules combined via heavy-duty fiber coupling. This distributed configuration provides excellent thermal dissipation characteristics, reduces component stress, and offers inherent power redundancy—meaning the system maintains operational reliability and output profiling even during extended, high-power factory shifts.

Question 2

Why is power instability held strictly to ±1.5% in ultra-high-power cutting?

Accepted Answer

When cutting heavy plates at 20,000 Watts, even minor drops in power can result in incomplete cuts or heavy slag accumulation, while power spikes can over-burn narrow slots. Maintaining power stability within ±1.5% ensures constant thermal delivery, producing perfectly uniform kerf dimensions, smooth side-wall profiles, and reliable micro-joints on complex patterns.

Question 3

What type of cooling framework does the RFL-C20000M-CE require?

Accepted Answer

Operating a 20kW multi-module laser requires a dedicated, heavy-duty industrial water chiller featuring dual independent cooling circuits. One circuit must circulate high-flow water to stabilize the internal laser diode assemblies, while the second separate loop cools the high-load output fiber optic connector (QBH/QD) to combat thermal lensing and safeguard optical clarity.
