According to US media reports, Boeing, the world's largest aerospace company, recently announced that its Compact Laser Weapon System (CLWS) has recently completed a series of key demonstrations with the US Air Force and the Army. The latest news shows that CLWS weapons with a power of 5 kilowatts have successfully completed several demonstrations of combat capabilities, verifying that they are ready for actual deployment. The test operator used a gamepad-like controller to lock and track small drone targets, and failed by firing a laser. Using the CLWS system fixed in a standard container, the system operator successfully destroyed about 30 targets on the first operation. Kurt Sorenson, Boeing CLWS project manager, said: "We have received a lot of feedback about the ease of use, maturity of the CLWS system, and its seamless integration into the command and control (C2) network. Over the past year, Boeing has been Five test sites demonstrated CLWS capabilities to military...

This is a  Q-switched laser , the wavelength is 1064nm. It’s a very popular Lab pulsed laser system. This laser does not have a CW continuous operation mode.  The power supply to  CW  is a mode for manually adjusting the frequency. Adjusting the current is to adjust the frequency, that is, to adjust the average power.
