505nm diodes in use!

[webdev77]

ooooh maybe they'll change to 488nm diodes

I'd love to get my hands on a 473nm or 488nm. They both have really cool colors but are too expensive for me at the moment.

 

[IsaacT]

Aren't both 473nm and 488nm lasers DPSS? That would be a pretty hard thing to incorporate into gun sights....given the whole recoil thing would be detrimental to the continued alignment of the optics.

 

[Blord]

What he said. The diode and solid state laser systems are more robust than the DPSS laser.
The recoil of the gun could devastate the laser.

 

[Apocalypse]

What if they made 448nm and 473nm direct diodes

 

[ZRaffleticket]

That was what I meant^

They exist, at a nominal fee of $4500

 

[luccax]

As far as I know it's possible to manufacture any wavelenght laser diode. It's not economically interesting because there is no use for them. If it wasn't for the c@s!o projectors we'd still dream about 445nm diodes.

 

[Apocalypse]

Imagine 580nm true yellow diodes.....

I think the best we've got right now is 589nm or 594nm DPSS and the more expensive 577nm OPSL

There's still a gap that diodes can't reach between 540nm and 580nm (I think 580nm was the lowest at room temp... gotta look that up again)

Crystal lasers make laser with wavelengths of 542, 555, 558, ( 561, which you have listed ),
584. The gaps are from 561-583 and 593-633

 

[ZRaffleticket]

Yes, but diodes aren't in that range. You can get any of those with a dye or tunable laser.

 

[Smeerworst]

I love them all, god stop with the numbers, i think i might go mad :gun:

Can't take it anymore!...

All of those wavelengths are using diodes. Check the site.

 

[ZRaffleticket]

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".

There are lots of diodes in the power supply for an ion laser. That doesn't classify it as a diode laser. A laser is classified based on what lasing medium creates the final output beam. The diodes in my ion laser do not create the output beam, and the diodes in a DPSS system do not create the output beam in any of your examples.

I bet in 6 months we will all have a 505nm build

Already have them. These operate anywhere from 505-515nm, but unfortunately it seems that we are a long way off from any kind of mass production/availability of these diodes.

I think he was aiming for "505's will be as common as the 445's"
