Photodigm has figured out a way to give us a mode-hop-free tuning range that’s pretty large that allows us to not have any mode hops to worry about in the area where we want to operate the laser. That’s a very nice feature. It makes tuning the laser to the exact wavelength we want a lot easier.

We needed to make a laser work at the wavelength of 795 nm, which corresponds to the D1 line in rubidium atoms. Photodigm engineers know how to make these gain medium for 795 nanometer lasers, with properties that suit our goals.

With all our vendors, they’re definitely one of the top for just being able to reach out to them to get something done quickly and authoritatively. For products as complicated as these, that makes a huge difference.

We have a pretty good relationship with Photodigm and we understand their technology, so there’s a comfort level and confidence in working with them.
