Finding a 12V Pulse Laser Circuit?

Hello,

I have a 12V laser module that comes with a built-in driver that's used for engraving. But I would like the laser to pulse instead of being a solid beam. I'm trying to find schematics for a pulsed laser circuit but they are all for low-voltage lasers (5v) can anyone point me to a good schematic for a 12v pulsed laser circuit?

Thanks in advance.

Edit:
I've been testing my laser and it does work at 5.7v using 1.13A while if I run it at 12v it only uses 0.67A so is there a good pulse laser circuit schematic/board for 5v-12V that will still allow my laser to burn?

Have you considered pulsing the 12 V power supply to the laser? E.g. by using a 555 based timer and a MOSFET?
