Instro lists all their current production as 1540-1550nm units see: http://www.instro.com/instro-products/lrf-modules/lrf100I've seen TO-3 mounted laser diodes (sometimes a c-mount inside them) but I've never seen one quite like this. I don't know if this is purely a pulse LD, or a CW LD being pulsed or what wavelength, but this is part of a Instro laser range finder rated for 5 kilometers.
This is possible, but in those cases the package is TO-3 sized, but has more pins - probably 2 for the diode and 2 for the TEC, unless they use the case as a common for both. With many of these IR diodes being case-positive that would not be a very practical solution though, and if you want to use TEC you would probably want to have to have some feedback lines too.I know TO3 packages are common when temperature control is needed in a small space as they can have a TEC and thermistor placed inside the housing
