Anyone have any info on a SDL-7470 diode? All I know is that they are 3 watt diodes which range in wavelengths from 645nm to 690nm. I got a 652nm diode and it seems to be perfect. I would love a datasheet showing a temperature/wavelength curve so I can see if I can get down to around 645nm or so. It's got a very small fiber core so hopefully it can be well collimated.
