It reminds me of a diode pump laser. We have a factory near by in Santa Clara, California, U.S.A. that makes diode pump laser. Those are corded models that requires a plug in AC 120 Volts 60 Hz here. This one looks like a cordless model. It can be a useful product for spot welding or small hole drilling in automobile body and fender repairs and drilling holes in circuit boards. It can be mounted on a mount like a photographic enlarger as a photon or laser drill press. There are lots of commercial and business opportunities here along with the liability of selling a cordless laser. Most cutting lasers at the Anthro furniture factory in Tualatin, Oregon, U.S.A. is a carbon dioxide tube laser, a very large unit. The air force has a giant tube laser and giant power supplies in a large passenger airliner jet platform that cuts missiles in half in flight. Epilogue, Colorado, U.S.A. has a laser mounted on an X,Y track that cuts materials like fabric, paper, wood, and polymer plastics. Circuit boards could be trimmed with this X,Y track mounted laser. Most industrial material cutting lasers are carbon dioxide lasers. This is the smallest one that I have seen, thanks for showing it.
