Good Morning Mr Kurt
It is an impressive little device – I forgot to look at the wavelenghts.
Thanks for drawing to my attention how confusing the article was regarding laser current (my bad). 0.3mA is the current drawn by the controller IC during emission – so I have altered the article to add laser currents and durations: 3-5mA is the short answer.

Very impressive! The product page says the wavelength is rather far into the IR range, which seems like the only choice for a low voltage device. Quite an interesting part.
