Soothsayer: Microvision’s Lance Evans “Green lasers alone are $200 each now”

It is just going to take more than 2 year for the brilliant people at the laser manufactures to figure out how to make the direct green lasers at a cost point that will lead to mass adoption.

The question is when will [Direct] green lasers be sold at a price, with the right wavelength, and are bright enough that they can spin up the market. Based on my 34 years of semiconductor experience and reading the “tea leafs”, I would say it is more than two years away (and a lot of people who know more than me about lasers say it is going to be longer)

that video even tho off topic is really Interesting
take a look at 2:57 that's amazing.

 

[Fenzir]

I'm not too psyched about 522nm, but 515 will get my wallet running. From the articles I read there was a 25mw 515. Interesting stuff, nevertheless.

 

[joeyss]

515 should be amazing at night....peak visibility and the beam gets scattered more than 532. Maybe 505 would be even better for nighttime beams?

This is pretty exciting news, thanks for keeping us up on the progress.

Next up hopefully they throw 20 of them in some cheap projector

 

[532 with Envy]

Hope springs eternal.

 

[Xer0]

years of green diodes only existing in theory, blue diodes at a cost of a brand new car...
...but once they want mass produce something with them, they become real and cheap

fu, economics. nobody thinks of us laser hobbyst

MicroVision sketches me out with their marketing tactics. I don't think they've actually innovated for ages now. I get news alerts for a number of laser related key words. Almost every week for the last year, MicroVision has released a "brand new" pico projector, with its own corresponding press writeup. However, when you actually look at each new product, you realize that it's the same "ShowWX+", but with support for XYZ different portable device. One week it's the iPod, the next week it's Blackberries, etc - which to the best of my knowledge has basically means a new SKU for a box with a different cable in it.

The company screams of desperation.

[weeba2kv]

They better effin hurry up with those demonstrated 4 watt blue laser diodes !!! stupid demonstrations WE WANT MORE !!!!!! power

 

[flogged]

Thanks for putting this topic together. I'm still waiting to add a green direct laser diode to my collection. It seems they've been talking about these devices for years now, however no diodes have been seen outside of paper/lab. I suspect they are more difficult to fabricate than is admitted to.

The most interesting new development (IMO) in the plethora of links you listed are the VCSEL constructs. Unfortunately they are very low power ( < 1 mW)

Any direct diode > 500 nm or < 620 nm is needed and very desirable.

 

[rhd]

A great way to keep abreast of this kind of news, is to use Google news alerts. You can put in keywords, and once a day they'll send you any new news alerts that match your search. It seems to filter out news releases from generic boring search results.

 

[aryntha]

+1, by the way, to madmacmo for aggregating this data and maintaining this thread so far. Thanks a lot! There's still more development to come!

 

[kguttag]

First, thanks for posting the link over to my blog.

I'm a major proponent of green laser's for all projection and especially for pico projectors. I have written and presented many papers on the subject. But as much as I believe they are the "the future," this future is not going to be in 2012, at least not in any big way. I talk regularly with many of the big player in lasers (and will meet with some of them at CES). My personal opinion is that Microvision is misleading people about the state of Direct Green Lasers (DGL) in order to prop up their stock price and to sell more stock to stay alive. But then when I tried to give the true picture on my blog, it ran afoul of what they had been trying to get people to believe.

I also understand that the laser beam scanning concept seems to those that haven't looked at it in technical detail like it would be small and efficient, but there are are a lot of problems with it when it is understood better. I'm not trying to bash the concept per say, but rather point out some of these often overlooked issues. I will point out where the LBS companies spread false and misleading information and when they accused me (thinly veiled) of being a "false soothsayer" then I will take issue with their false claims.

While the controversy with Microvision was good for driving some traffic to my blog, I would really like to see more questions that have to do with laser projection in general and less on LBS/Microvision. So please feel free to come by and ask questions.

I haven't read your blog, but I do have the sense that Microvision is up to some sketchy marketing. I'll tell you why I say that -

I subscribe to press releases, and one of the topics I have a bunch of saved recurring searches on are pico projectors.

Well, for a pretty large portion of the year, I was getting press releases almost every week, about different "new" pico projector models that were being released by Microvision. Although it may be an exaggeration, it certainly felt like there was a new model being announced every week, for a period of many months.

Of course there weren't actually any new pico projectors. Microvision would just send out a new press release, claiming a "new model" any time they added a hardware partner. I got the press release about the ShowWX+ that supported Ipod, and it was this great "new pico projector" from Microvision. Then there was the pico projector model they released for BlackBerry, which again was promoted as a "new pico projector", even though really, I think it was just the exact same product with a different cable. Then they got really sketch-bag, added an HDMI cable, and started selling the "ShowWX+ HDMI". Again, it was billed as some great new pico projector, but it was the same unit, with the same specs (brightness, resolution, size, weight, look&feel, etc), just with a slight tweak to the name and a new format to support.

There are a number of examples like this, where Microvision tried to repackage the same stuff as something new. I got so sick of reading it, that I stopped subscribing to pico projector press releases all together. It really stunk of desperation. It's fine to be desperate in reality, but when you look that way, something's wrong. They were trying way too hard.

I don't understand what their stumbling block is at this point. Everyone is blaming their financial situation on the delays associated with direct green diodes, but I think that's bologna. If Corning has no more of their tiny DPSS modules to hold Microvision over until direct greens are affordable/viable, then there are lots of other options. Snake Creek has stuff that is as small as the Corning units (LaserHeads) and I've got a little DPSS "pico projector" crystal set that I bought on eBay for $99 that really wouldn't add any substantial bulk, even when coupled with an IR diode.

In other words, if Microvision is in trouble, it's not because of direct greens not being here, it's because they're doing something else wrong, somewhere.
