YAN(G) Laser Logo Design

I'm delighted to share another logo from my archives that I designed last year. This is a special logo for me because it was designed for a friend of mine who runs a laser business. He asked me to create a very simple logo so he could put it on his devices. I wanted to combine letters "YL" in the group in order to be able to use this composition separately according to his needs. What can you say about guys?

Below are some other versions of the logo, from which we have chosen the best one ↓
