These 635 nm lasers are similar in colour to the 632.82 nm line of the Helium–Neon laser. Nobody calls the red He-Ne orange! You can clearly see this once you compare it to the orange 611.80 nm line (3s2 -> 2p6) of the He-Ne. These diodes are orangish red, but still red. I bought a 400 mW of these diodes once and was a bit disappointed because I didn't know that the mode pattern was squarish, it was not the beautiful round TEM_00. But still quite brighter than the ~650 nm diodes.
