I recently purchased a Laserbee I LPM and took my first measurements with it last night. For each of the lasers 635nm (direct diode), 532nm (DPSS) and 473nm (DPSS), the most immediate thing I noticed is that the levels measured were quite a bit lower than I was expecting. And in the case of the green and red, lower than CNI's test reports accompanying the lasers.
I have read elsewhere that one needs to allow time for the lasers to warm. But how long is long enough?
Also, I'm assuming that these measurements should be taken with an analogue drive signal of 5v (no more, no less). I have noticed when I accidentally, and very briefly, over supplied the analogue signal, the power output was visibly higher. Could it be that the drive signals need to be higher than 5v?
Clearly if the CNI lasers prove to be much lower than specified, I am keen to resolve this with them. So I need to ensure I am not mistaken.
Thanks in advance.
