505nm diodes in use!

[steve001]

Using IR diodes and crystal sets through DPSS, yes the gaps are smaller. What you're saying is the equivalent to saying "we've had green laser diodes for over ten years".

It doesn't matter what they may say, it's known that 542nm is frequency doubled from Nd:YVO4's 1084nm line, 556nm is frequency doubled from Nd:YAG's 1112nm line, 561nm is frequency doubled from Nd:YAG's 1122nm line, 589nm is Sum Frequency Generated (SFG) from Nd:YAG's 1064nm and 1319nm lines, and that 593.5nm is generated from Nd:YAG's 1064nm and 1342nm lines.

The other ones listed are through THG and other means I haven't yet learned. But I can assure you, they're NOT simply diodes.

Their bullets even say "diode-pumped".

I think you misunderstood me. I never stated or implied they were directly driven diodes. I just pointing out that diode lasers are available that you said weren't available in certain segments of the visible spectrum.

I don't think you're getting what we're saying, DPSS ≠ diode lasers.

I know dpss diode ≠ a directly injected laser diode. But reviewing the posts I see where the misunderstanding occurred. I was simply talking about the wavelengths commonly available, be they directly driven or dpss.
