Hello All, I decided to create this poll to find out what everyone's desirable wavelengths are. If within the next 5 years, your favourite could become accessible (low enough cost for hobbyists), what would it be? It can either be in diode or DPSS form whether already in existence or not. If your wavelength is not listed in the poll, click other and write a post of which you would choose and why (optional). As the forum only allows up to 10 options I will update my post to include anyone else's suggestions.

Here is a quick analysis:
420nm - 1 - 4%
Still very expensive to get hold of in diode form. However it is possible. Here is a 430nm and the company offers InGaN diodes in 5nm increments.

Well we done very well in this section. A sudden influx of cheap diodes came our way very soon after this poll begun. 2016-2017 saw a boom of new wavelengths reviving the community. All of the cyan section became covered with cheap and powerful Class 3B diodes. And where the cyans stopped 505nm diodes tookover. Pretty much the entirety of cyan-aquamarine section is now available to the hobby. The only sad news is that the 480nm diodes dried up that came along with the 505's.
555nm - 3 - 12%
Still rare and expensive unfortunately
575nm - 1 - 4%
580nm - 4- 16%
Another surprise turned up when mysterious new DPSS lasers turned up at 565 and 575nm. Even more bizarre was they was cheap. Unfortunately some suffered crystal degradation. However word has it, that we should keep an eye out in the future for a return of these wavelengths.
595nm - 0 - 0.00%

As expected, orange still remains elusive. Only expensive means to get hold of wavelengths in this range. Whether it is DPSS or supercooled red laser diodes.

Very interesting to see what wavelengths people wanted to see available and what actually happened.

Holy @#$%... $100 488nm diode!!
Hello folks! I've recently been looking around for 488nm diodes. I never really had any success finding anything less than $1000 (or any company that would reply to my emails at all.) Then I contacted Semicom Visual a few weeks ago, and promptly forgot about it. Today I woke up to an email...

505nm and 480nm diode RESULTS
That's a nice beam shot of the two you have, Atomicrox. That 480nm is a Sharp diode that turned out to be between 473nm and 478nm? I was wondering as I am not aware of a 480nm diode that you might have used in its place. + Rep.

Sharp GH04955A2G/ The New 495nm diodes
This is the Sharp #GH04955A2G, 495nm laser diode. Unlike earlier versions of 480nm and 505nm, these have no micro-printing around the diode's window. These new diodes are difficult to describe in terms of their color. To me they are right on the edge between blue and green. It is a spectacular...

565nm From LaserLandAustralia
Lets start with an obvious question. What Color is 565nm ? Next. The One that everyone wants to know. The Wavelength. An Expanded view of the Spectrum. This DPSS laser has quite a wide bandwidth. Ranging from 565nm up to 571nm. That is quite wide for a DPSS laser. It's obviously not...
