Will Yellow DI Laser Diode exist in the future?

[JRGixxerfreaK1]

Hello!

Im just curious , since nichia and others are able to manufacture multi wavelength laser diode example Nichia's 475-+nm diode

Would today's technology be possible they could create yellow DI diodes 560-590nm range?


Cheers!

As far as I know, CNI already done them...

If you are referring to the 589nm and 593.5nm they are both a DPSS system and both use sum frequency generation to create the yellow .

Id guess in time, yellow diodes may show up .

Only if they can find good use for them, and I dont see any good uses yet.

The use would be to drain my wallet

Duh, never answered your question. Yes. For the life of me I cant remember the company, but they can create just about any wavelength in diode form. An old friend of mine had a 100mW 622nm diode built for ~$800 IIRC early last year. I looked through all my links, and emails and cant find it. Sorry.

I believe the 520nm diodes and down to 405nm are all GaN junctions with engineered strain created in the crystal lattice to allow the different wavelengths to lase. That is why the wavelengths are imprecise and diodes of the same type from different batches lase as much as several nm apart. I think the 520 nm band gap was hard to achieve and the crystals were fragile.

I examined a 638 nm laser through a monochromator after I drove it to LED and the narrow red beam dimmed a great deal, but the color then spanned from above 780nm down to 530nm. I thought that if the cavity mirrors were designed to oscillate in the yellow-orange in the first place that this diode might lase there as well. I even posted this sometime back, but I can't remember where.

The diodes I'm talking about are all TO-18.

Thanks for the info guys!

I got myself a 1W 579nm Diode!









Hehehe Kidding :P
