Wavelength Modification Help

Hi, I have been using my Moai for the past couple months with the Moai Resin and everything is working wonderful.

Recently I wanted to try a new project which requires Resin which is photopolymerized with 385 nm, and as you all know the Moai provides 405 nm.

My question is how can i modify the Moai in order to get the 385 that i require?
Do I simply change the parameters (like laser power) and if so which ones do you recommend?
Or do I have to buy a new laser, and if so which one would you recommend.

Thanks in advance
