Dear all, this is my first post. Now i want to build 20mW 660nm laser pointer. But the only laser module available in my country is 5mW. If i order laser module from internet it'll need 3 to 4 weeks, it's to long. My Question is, can i have 20mW optical power output if i combine 4 laser module @5mW in one cluster?
