High efficiency scrubber for waste gas abatement

A gas scrubber comprising:

• a gas inlet pipe that provides the gas scrubber with gases to be processed;
• a chamber of decomposition to which is connected the gas inlet pipe that delivers the gases to be processed, such that the gases are decomposed into a plurality of different byproducts through a thermal process in the chamber of decomposition;
• a transparent means through which light can pass through, mounted onto the gas inlet pipe before the chamber of decomposition;
• a laser device arranged before the chamber of decomposition such that a laser beam, output by the laser device, passes through the transparent means and the gases flowing in the gas inlet pipe to decompose the gases into a plurality of gas radicals to initiate the reaction of decomposition;
• means for cooling down the plurality of byproducts produced in the chamber of decomposition;
• and
• means for scrubbing the plurality of byproducts produced in the chamber of decomposition.
