WebRed laser diodes are often used for laser pointers. Various gas lasers can emit red light. In particular, helium–neon lasers are suitable for smaller powers at 632.8 nm, whereas krypton lasers can generate high powers at 647.1 nm. Lasers based on praseodymium-doped (and sometimes ytterbium-codoped) ZBLAN fibers can emit around 635 nm.
