Heya.
I have been dealing with a company named "Photoelectricity Technology Stock Co. ltd", seated in China. Proclaiming they could deliver 671nm DPSS red modules at a very low price (starting at $12). Even sending out a word document with pictures and 671nm DPSS specifications upon request of detailed product specification.
As the anatomy of the red DPSS is (as I understand it) similar to the green DPSS I figured that it might actually be possible.
Ordered two modules at 20mW. Totaling at $24 + $15 shipping.
Received regular 650nm direct modules. Mostly as expected.
No regrets. Will probably ask them to ship out one of their green high power modules to test power output and update with results, if they don't cut me off as an "complaining annoying customer" which isn't worth doing business with anymore.
Was in touch with another company in China which provides 671nm modules. 20mW @ $233. 50mW @ $288. Making the GB a lot more attractive. However one interesting fact was that she couldn't find any reseller where she operated selling 671nm modules smaller than 25mm diameter. Rather large.
Can you owners of 671nm pointers describe if this seems reasonable for the modules used in your portables?
