Let's hear all your laser hobby related predictions. I plan on updating this thread in the future and giving credit if anybody is actually right.

Ground breaking advances only please.

Here are some examples of past advances.

Green DPSS becomes common and affordable
-Blu-ray 405nm diodes become available to the hobby community
-445's come out and change the scene by providing the community with super powerful diodes at an affordable price.
-High power 638nm diodes start becoming common.
-465/462 diodes come out providing the community with some truly blue looking diodes.
-Green laser diodes come out
etc...


Personally I'm betting on combined RGB diodes of some kind. They won't be truly white, but they'll be close.

I'd like to bet on yellow laser diodes, but I really don't see any real demand to drive development. If you want yellow for a projector or light show you can just mix red and green. Green/Red/Blue laser diodes all had a reason to be developed. We're likely to be stuck with expensive and unreliable DPSS yellow well into the future IMO.

Predictions:
combined RGB diodes.
Cheaper 488nm diodes.
X-Ray laser diodes.
10+Watt blue diodes.
Cheaper diodes in the 470-490 range.
Yellow diodes.

Agreed - RGB diodes are going to start a craze here in a few years' time. Also agreed that yellow diodes aren't coming any time soon :(. I'd also like to add that 488 diodes might become widely available soon due to the medical applications.

My main hope is that there will a drop in the price of the 488 diodes and they will start to become more readily available to hobbyists. They do have real uses, so hoping that causes them to be produced in greater quantities.

Yep, think with yellow we might be stuck for the time being. There seem to be limited uses for that color and there doesn't seem to be any progress in direct yellow diodes. In fact yellow might actually get scarcer if CNI stops making portable yellow DPSS as there are no other manufacturers of portable 593.5 or 589nm lasers.

I was thinking of a triangle wave guide inside the diode with a RGB emitter one on each flat of the triangle waveguide, then by modulating power you could have many mixed colors as the beam diverged into the distance it would look like a white beam or color resulting of the RGB mix.

In 5 years times Styropyro got his laser physic degree and create a anti mater positron laser diode:D and got nobel price for it.:D

Yeah, that would be pretty awesome. No reason why it shouldn't be possible too.

X ray laser diodes will be interesting and dangerous, possibly restricted, but I hope not.

Short wavelength UV diodes are another one I've thought about. We have 365nm and lower LED's so it should be possible right?

Personally, I hope to see a Ti:sapph summed with something like Er:glass in a broadband nonlinear crystal to create a single-frequency laser tunable over the entire visible spectrum. All in a portable package of course. :p

Seriously though, I think we'll see diamond lasers make an appearance in military applications, and possibly the return of alkali-vapor for the same reason (DPAL).

For us hobbyists though, I think the biggest thing will be the 488nm diodes like others have been saying. For the next few years most of the new and exciting things (for us) will probably come out of the hobbyist community itself, rather than the professional industry.

Room temp maser systems have recently been developed, so I'd really like to have one to use as a highly directional radio antenna. If we're talking serious power, maybe even a long range popcorn popper.

Also, yellow diodes. Make them for astronomical guides stars so they're in the multi-watt category and have great divergence specs. :D

Otherwise, I'll second a multicolor combined diode and reduced costs.

Screw the laws of physics. Get on it Styropyro. I don't want to burn things. I want to ANNIHILATE them! :crackup:

X ray laser diodes will be interesting and dangerous, possibly restricted, but I hope not.

Unfortunately another physically impossible one. Maybe a smaller, cheaper method could be found, but some sort of new state of semiconducting matter would have to be found to make something small and easy like a diode.

Good thread idea!

Hopefully we see more advancements in the 565nm-585nm range. Some pretty interesting colors there :)

Yeah yellow diodes would be great, I just don't yet know if I wanna spend $530 on a 589 Spartan. I'll bet it's a true beauty to all that have one though.

I'd bet on cheaper diodes in the 470nm to 510nm range in the near future. And 10W+ blue lasers.

Combined RGB diodes would make me the most excited. Would open up a lot of doors.

I can't think of anything that hasn't already been mentioned.

Maybe some kind of cheaper/smaller/faster scanning galvo tech. Not related to pointers but it would be a godsend for the projector folks

Yes please:eg:
If they ever were a thing they'd probably cost a ton though. Such a specialized use means they wouldn't see much mass production. Same with the current 488nm diodes which are used to replace argon lasers.

Yeah, they'd definitely be bank breakers. Especially since laser guide stars are used on pieces of equipment where one relatively expensive component might be in excess of $1,000,000.

At least they'd exist though. More chances at surplus high power DPSS and dye lasers for us until they got cheaper. Maybe if the other adaptive optics components got cheaper and easier, smaller research institutions would have a mass exodus to modern telescopes and drive diode production up.
