Question: which of your lasers has been most useful ?

I’m hoping that the lasers I am working on now will be the most useful. They are for a big optical communications project that hopes to research new and improved ways of making faster internet for everyone. My research is just one small part of a bigger project, but in a couple of years everything will be brought together and hopefully it will be successful!
