Natural Science Forum / Physics / Optics / October 20051450 nm Laserdiode? Who sells them?
Dear group. Can anybody inform me about who sells 1450 nm laserdiodes? The ones I contacted so far did not have any in stock and I need some quite fast (CW type 5-10 mW) I will use it wiht a lens as a collimated light source (no fiber coupling). Best regards Kasper Paasch Denmark. > Dear group. > > Can anybody inform me about who sells 1450 nm laserdiodes?

How close to 1450 nm do you need it? Try: http://www.roithner-laser.com/LP-laserdiodesIR.htm --- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name is included in the subject line. Or, you can contact me via the Feedback Form in the FAQs. Thanks, but I already tried Roithner. Their 1450 nm LD is not in stock and the 1460 nm LDs are a bit off wavelength as I need it for a spectroscopic setup.

The diode you get will be slightly off in wavelength. In addition, the actual wavelength that you get will change with temperature, about 0.25nm / degree C if I remember correctly. > > Thanks, but I already tried Roithner.

I ordered one with similar wavelength from meredith instruments a year ago, they stock them as TELCOM surplus on their web site. It was fiber coupled, ~100 mW, and 62/125 (really small telcom type) fiber. Steve Roberts |
