it could be using the TL494 PWM control IC that is very often used in ATX computer power supplies
TL494 data

200W ATX PC POWER SUPPLY
I would expect it will have a switch mode power supply circuit to power the Laser control circuit and an EHT generator circuit using a flyback transformer very like the one found in the old TV's & Monitors that used a CRT (cathode ray tube)
