Undervoltage shouldn't hurt anything. But the laser probably won't work very well either. 3.0V on a li-ion means it's time to recharge. It'd be like running the laser with a dead battery.

I don't think 3V will be a problem.
A green module will run fine on 3V, and no other laser will work properly on just one 3,7V without a boost driver.
There would be a problem if it was two 3,7V batteries, then you might have a linear driver, that would work with 7,2V but not 6V.

You cannot fry a laser if you use lower voltage then reccomended.
You can mosts certanly try out your laser now.
Qumefox, 3.0V cell is usually pile lithium, can also be rechargeable with cycle of max 3.7V and minimum 2.0 V, unlike lithium ion cells 4.2 - 2.7 V.

It was my understanding that rechargable cr123a's were really li-ions. 16340's to be exact.
*edit* nvm. google tells me the 3v ones are LiFePO4's.

17650's are going to be slightly smaller than 18650's.. The numbers are the physical size of the battery. First two digits are diameter, next two are length, and last is form factor. therefore 18650 broken down is 18mm in diameter, 65mm long, and the 0 means it's a cylindrical battery.
A 17650 would be 1mm smaller. Probably not enough to matter, but i've also never actually seen a 17650. My guess is they're made to have protection circuits added, which generally adds 1mm to the diameter, then get sold as 18650's.
