Idk if rare stuff like handheld 577nm will come down much. That requires a decent demand for the product to drive manufacturing efficiency improvements. At $1500+ for a 3-5mw pointer, I doubt there will be much of any demand to drive this. Most professionals want a lab unit, and only the wealthiest of the hobby crowd can afford stuff like this.

It's a similar problem with 589 and 594 lasers. Haven't seen any significant price reduction or higher output over the past years. The DL units have actually gone UP in price.

I think we're at least a lot more likely to see a diode in this area than 589/594 though. It's at least a color that'd be useful in high end projectors and lighting systems, so maybe we'll have a bit of luck.

I agree that the price of this DPSS won't change much though. The complexity is too great, and there just won't be enough demand at the necessary price range.

ya know, maybe with the new diodes coming out i can predict there being a diode in the green yellow orange range sometime next year :yh:

Maybe. The sad part is that commercial diodes seem to come out in batches and have long breaks in between. I'd say if it keeps up longer, we could see a much better orange 600-615nm (they already exist) or a ~560nm max diode. A 595-600nm scientific diode could pop up sometime soon though.

I highly doubt there'd be a true yellow so soon since semiconductor science isn't quite there yet, and it takes a few years to trickle down.

577nm lasers have been in use for a long time in medical applications. Companies are working on diodes in the yellow-orange region. http://laserpointerforums.com/f40/quest-yellow-orange-semiconductor-diodes-101018.html

I'm aware of the uses and the means. The reason I believe true yellow is more likely to be commercially available is because it can have more consumer applications.

The quantum well tech is likely to provide a yellow-orange diode sooner, but the applications are likely to be more limited and manufacturing less developed. Medical diodes don't have the kind of demand that helps us out much.

The articles people frequently link in those threads aren't good indications of timeframe though. They almost always reference academic semiconductor research which is a lot farther away from reality than a company's R&D.

Look at 405nm diodes. They were developed in the early 90s, but we didn't see them much until more than 10 years later when manufacturing and applications matured.

Not to sound pessimistic, but it's part of the only industry I've really worked in. It just shouldn't be too hard to figure out if a groundbreaking diode is that close to reality.

i would like to see 445 in consumer lighting. ive found that the color from my 445 with my rooms incandescent bulbs makes for a pretty warm purpleish yellow combo. the mood it sets is super cozy. i used to do it with my black light but it was hardly noticable on things that werent white.
 
I'm late to the party showing the beam shots, just saw them today. Appreciate it much, I really wanted to see that :)

Alaskan, you'll need to show us some pictures once you get that 577 going! 3W's of 577 must look amazing at night ;)

Man, how'd I miss this thread? nice man. good color representation in your picture too. it captures the difference pretty nicely.

As for the process, yeah i'm pretty sure its a linear Yb laser with custom coatings.
