Chinese RGB laser 1w : hardware lower output power

Hello

Quick question, i have a chinese laser RGB 1w total analog 30kpps (the one less than 500$)

But my question may apply to other basics models

is it possible to lower each diode laser output power ?

exemple :

green is 200mw and i want to have max 50mw

same goes for other colors.

I know that could be done with software but for pratic and safety purpose i want to lower the max level

Otherwise do you know if there is any analog lower power laser diode on the market ( around 200mw total )


Thanks
