Laser for practice/demos

Hello,

I’m an individual artist who rents lighting/projectors at venues. I’m interested in adding lasers to my set but don’t have any experience with them.

Is there a way to emulate laser (or are there affordable lasers <2k euros) that I can use to test and practice my performances with?

I’m new to working with lasers so any advice is much appreciated.

Thanks,

THT
