Well, its just physics. The process can be made more efficient with time and work, but its still inherently very inefficient. I don't see yellow DPSS really coming down much because as BenM said, there's also very little demand. What may happen though is in the upcoming years, as more and more wavelengths are attained with direct-injected diodes, we may see direct diodes in that wavelength just like red diodes. Still, demand would probably be low, but it'd be an opportunity for 100mW of yellow laser light for a relatively low price.Medussa said:I wonder if this complex DPSS process concerning yellows would get rectified or there would be some sort of innovative techniques concerning yellows in the future. I think a high powered yellow laser would definately be cool as heck. To bad on what there is to offer on the market concerning yellows.
in 10, 20 years will i finally get a 488nm pointer due to nanocrystals??Justin said:There have been some advances in nanocrystals which should allow for direct diode lasers of any wavelength in the future (See www.scientificamerican.com), but you won't be seeing them in a laser pointer any time soon. Until then we are stuck using DPSS technology to create solid state yellows.
oh i know about *those*, but i have to wait til i win the lottery before doing thatpseudonomen137 said:There are 488nm DPSS lasers actually! I'm sure if you have a few tens of thousands in spare change you could contract a company to make you an IIIA pointer
