The newest Data sheet online from Ushio says "Single Transverse Mode", the Single Longitudinal Mode was simply a mistake. However they may be fine for Holography and I will test a couple soon on a 2GHz FSR scanning interferometer to see what the real linewidth is, Remember HeNe;'s ate around 1.5 GHz so anything under that is fine and these may have a longer coherence length than HeNe. However they are almost certainly NOT single frequency...not "SLM"

The parcel has arrived. Everything is safe and sound.
Next week I plan to test, I inform about the results. Now I'm doing an emulsion at 640 nm. for this laser.

Ok any feedback on these units ? I noticed there’s a projected pinhole approximately 10” ahead of the lasers output, by placing your optics @ that distance will provide a nice clean output ..

Ok if any one wants a complete red system, do the purchase on eBay (listed as head only),and I’ll include an extra red module or driver for said laser, if you do make a purchase, send me a note to include which extra u want. Thanks DB

Don't Bogart the driver.

Hi Dave. Payment sent.

Ok finding that once it’s set In SLM, just leave it on ! With my simple driver and only passive cooling remains locked in . Turning it off/on again losses SLM and need a reset...

After looking at some more datasheets, I think you're right that +50C refers to the maximum, and this seems to be typical of red laser diodes, as shown at:

https://www.thorlabs.com/newgrouppage9. ... group_id=7

For red diodes, the operating temperature of 0 - 50C is often given. So this diode seems usual in that respect. On the other hand, I think Dave mentioned that these particular diodes like to run warm, and this may be a useful observation.

Hi Dave.
Is it possible to buy with drivers?
How much ?
Valery.
