Laser and Photonics Patent Classification

Laser devices classify in H01S: everything that amplifies light by stimulated emission, from semiconductor laser diodes to high-power industrial sources.

The optics around the beam, lenses, waveguides, optical systems up to AR headset optics, sit in G02B for optical elements and apparatus.
