Turning on CNI PGL-III-C-589 continuously for at least 2 hours

[cephy]

I'm new to this forum. I'm planning to purchase a PGL-III-C 589nm 80+mW. I understand that this laser unit is designed for 1-2 minute ON duty. Is it possible to actively cooling the laser head so that it can be turned ON continuously for at least 2 hours without damage? If so, what temperature should the laser head to be maintained at? How stable is the power of this laser?

thanks in advance for any suggestions and ideas,
rob

If you want a laser that can continuously stay on, I'd recommend getting a labby. Would be more stable too.

Contact Justin from Laserglow.

He may have a Vega HV for you.

I suppose a proper mount for the laser could be machined and built around the unit to cool it by including a large TEC/heatsink/fan combination. It would be very interesting as a project to attempt/

Why would you need a pointer to be on for 2 hours?

I'm contemplating whether I could save some $. I know a labby would be ideal. The laser needs to be on continuously during the experiment, and the beam goes through a mechanical shutter and other optics in the system.

~1% optical efficiency from a 589 doesn't lend well to large duty cycles. So here's the thing, yes you could probably run this PLC continuously, but if you ignore CNI's duty cycle you'll suffer from instability, great power losses, and maybe even a pulled warranty if CNI finds that you've been running the thing constantly.

Whatever your experiment is, it will not be getting power stability or even 50mws after 4mins.

Labbys are made for experiments, use a labby.
