I do understand how difficult, and unstable yellow/orange lasers are and that's obviously why they're pretty pricey, but does anyone think 556,589,593 etc. 500mw/1W lasers in handheld form will one day exist and somewhat affordable as well? I'm just not that familiar with those wavelengths. hope this isn't a far fetched or stupid question, thanks

I'm certain it will eventually happen. It's just a matter of time really. How much? Can't say for sure. But in the mean time you can build a mini projector or beam combination you can get most of the colors you want.

All those wavelengths exist at powers of 500mW+ But in labby form, and for a reason! Unless a new technology is found its highly unlikely! IIRC 556 is pretty efficient but yellow lasers(if not cooled) release a ton of heat. Take for example a 5mW 593.5/589 pointer/handheld, after 1 minute those devices start to get hot & if run for too long will destroy your laser!

Too get 500mW of yellow in handheld form would not only require a large bank account(currently) but a method which can effectively deal with the ton of heat produced:)

No. There's no reason to, and even based on efficiency there's no way to- you are talking about a ~50W pump source for 500mW of 593.5nm output, or a ~16.5W pump for 500mW of 589. And that's assuming everything else is perfect.

Plus, there's no market. No commercial industry wants/needs 1000mW handheld yellow lasers.

Very true. I use to be a huge flashlight enthusiast, but that hobby has been put to the side recently because I find lasers so fascinating, I've only got a 445 and a 532, and I really want a 473 but those are pricey too. Couldn't even imagine how elegant that color is. Thanks again for the respond

Wow! Freaking incredible! Def didn't know that. I'm somewhat new in the laser world, and love learning new things, thanks so much Alex :D

Definitely makes sense, i appreciate the reply :D

i think that maybe eventually the color will be developed into diode technology for some reason or another, then possibly we will see those high powers cheaper, just like with green, however i don't see that happening soon.

also, please avoid posting on a thread multiple times in a row, try to consolidate your comments into one.

Richie89 - Please do not double and triple post. If you want to add something it is better to edit your current post and add it to that.

Just a friendly reminder before you get blacklisted :)

And power isn't everyting. There are LOTS of wavelength hunters on here. Trying to get every freq out there.

473 is very cool and if you are fortunate and carefully watch, you may be able to pick up one without breaking the bank.

I bought a BLM-100 473 ($2000 list new) for about $200 a few years ago - Pristine condition.

There are also some lower power, 5-25mw range, pulls from equipment. But be careful, they are very touchy and have tons of splatter. There was a time when you could pick one of those up for about $35.00. There may still be a few out there, although the price will be higher on them.

It probably will happen one day but surely not with today's technology. The main thing that will drive that is a demand/specific application for those WLs. Then the effort and capital investment will be put forth to develop those WLs in a cost affective diode.

Maybe consider mixing colors to make yellow? Won't be real 589, but can look quite yellow and if you get the right red and green diodes matched up to some good optics, the beam might look like the real deal.

That's an awesome picture.

There isn't a proper semiconductor for yellow wavelengths yet, which means more research needs to be made before one even becomes available. Unfortunately, yellow when compared to other wavelengths and their uses is a lot smaller which many companies don't find the money needed for research worthwhile. Now, don't get me wrong, a diode based 589 laser would be sweet, but I think it's safe to say we'll be seeing DPSS yellow for many years to come!
