For whatever reason, they were giving you information for which you had no reference. I tried googling 74,75,76, etc. and it turns out that these are numbers.
But on a more serious note, it looks like they are talking about Mitsubishi laser diode part numbers.
I looked it up last night. Only found results for 72. The other don't appear to have any relevance to diode part numbers. So I'm pretty sure they were semi-trolling.
