I thought this could be an interesting (and colorful) thread to keep updated. The idea is to track current diode laser wavelengths.
My proposed guidelines:
- Only visible wavelengths from 390 to 750, and only pure diodes, not DPSS.
- Cite sources unless it's a common wavelength
- Package type (9mm, 5.6mm, C-Mount, etc) isn't important, but something clearly outside the realm of portability doesn't count.
- If wavelength is given as a range, take the midpoint, and if that gives a .5, round up.
- Differentiate between (C) common OR cheap, (E) exists but impractical or costly, and (R) rumoured or anounced.
- If a particular wavelength has more than one entry, in different (C,E,R) letter categories, the most favorable letter will be indicated (C>E>R)
I'll give this a start:
375 nm - (E) - Nichia NDU1113E / NDU7216E
405 nm - (C) - Multiple manufacturers, Sanyo, Mitsubishi, Nichia, etc
415 nm - (E) - Roithner RLT415-200PMG
440-460 nm - (C) - Nichia, OSRAM, Opnext
473 nm - (E) - Nichia NDHA210APAE1 (likely same as Thorlabs L473P020MLD)
488 nm - (E) - Nichia NDB7352 (likely same as Thorlabs L488P060MLD
505-525 nm - (E) - Nichia, OSRAM Announcement
523 nm - (R) - Soraa Announcement
531 nm - (R) - Sumitomo Announcement (2009)
622 nm - (E) - LDX Optronics LDX-2106-622
635-685 nm - (C) - Multiple manufacturers, Mitsubishi, Hitachi, Sanyo, Opnext, Eudyna etc
It will sure be nice to see some of those Rs become Es, and Es become Cs
Lets keep this updated as news pops up!
