It turns out that this laser is the same one sold by laserbtb.
Actually lasersbtb offers two models, 30 and 50mW. Which uses Osram 515nm 30mW and 520nm 50mW respectively.
Do you notice any color difference between low and high power mode ?
If you go in laser diodes section in their website you will find Osram 30mW 515nm and 50mW 520nm. Now if you got to their HL series you will find it listed the same way.I don't notice any difference in color between the power modes. Also, I am looking on laserbtb now and I don't see this 515 5P-30, I only see 520 5P-30 and 520 5P-50 (didn't see the 50mW at first as they have a typo in their add to cart box). But this particular model is 515 5P-30. So I don't believe laserbtb sells this 515 as far as I can see. But yes those 520 5P-XX are definitely the same host and features as this 515 model.

As for the pointers they messed up the naming a little. If you scroll down the page in the table there is two models LF520-5P-30 and LF520-5P-50 which is obviously Osram 30mW 515nm and 50mW 520nm also there is a link to a data sheet below the table which shows PL515.
I emailed laserbtb about it. I am curious because they clearly are labeling these both as 520 5P-XX when these from berlin lasers are labeled 515 5P-30. I guess what I am wondering is if there are 3 different lasers we are talking about here instead of just 2. Our model is labeled 515 5P-30 and theirs are 520 5P-30 and 520 5P-50. It seems clear that our models are the 30mW 515nm diodes. But what I want to know is if their 520 5P-30 is really the 515 5P-30 like ours or if it is actually using the 30mW 520nm diode.
