Hello,
This is my first post ever.
I want to confirm the output power of a laser unit that I bought from eBay. I have a nice laser power meter from another disassembled laser, two in fact, but I can't find any info about the meters online. You can see the meter in the photos below. The numbers on it are PC1064A on the PCB and AP2027100 on a label sticked on it, but nothing comes up when I Google them. It has an OP07 op-amp IC as a voltage amplifier, which was the only useful info I have, because there are datasheets available for it. So from that I was able to figure out how to connect power and read the sensor by looking where the pins from the IC go. I get about 1.5V reading on the output pin when aiming the unconfirmed 20W laser. But I really don't know how to interpret those 1.5 Volts without any info about the sensor. Therefore, I can't really confirm the 20W power, which is what I'm interested in. So all I really need is the Voltage/Power ratio for the sensor and if it stays linear over the range. Does anyone here owns a laser like that or knows anyone who might know about it? I also attached a photo of the laser. It's a 100W Yag laser. Any lead on where to look or ask would be very helpful.
Muchas Gracias.
P.S. I'm a laser noob at the moment.
