You won't find a more knowledgeable person here than Singlemode Laser. I have done business with him too and I highly recommend him as a person you can depend on.

You know something I don't? Or did you just mean in general, like losing interest.

I don't know why pullbangdead is no longer active. It was a general statement. Everyone leaves eventually........out of lack of interest, time constraints, even death.

I sold the last 505nm diode to a friend of mine. No 505nm diodes more available and planed in the future.

I hope that these new 495nm diodes are real and can be bought soon. I am planing to buy ~10-20 of them
to pick the ones with the wavelength I need and sell the the rest with a wavelength measurement sheet to
the members of this great forum.

PS: Thank you paul for your trust and your words, I really appreciate it from you, a member who has a deep knowledge in this field himself!
(and who is a very nice person to communicate with!)
I am considering myself as an expert in the field of diode lasers and l don't look to compare myself with other people,
but look to learn an contribute as much as I can. T

I'm glad you sold off the last of your diodes and for the extremely kind words, Singlemode. I am still waiting to hear about the 495nm diode. Send me a PM and I will talk with you more about this.

How and at what current did you measure the wavelength? I'm measuring 509nm at 108mA with no lens.
Since the spectrometer before recalibration was reading ~1nm too high, I have to correct my finding to 508nm.
