Copper Bromide Vapor Laser pulsLight CBL-05m

[Picasso]

Just got the pulsLight CBL-05m home. Yes the one from ebay. I need to give it some love, need check out the PSU being able to take 240 2-phase. I think this is mono phase only. Plus with the scanners on it I need to check how those feed off the main plug. High and Low setting for heaters voltage dependent? The temp display/controller is in the projector aka you can never view it with cover in place. This cracks me up. temp reading from the LASE facing side. Ugh I'm going to move it. I will need some help with the DMX stuff I have never worked with it. Here is a pic of the scan setup. I could not get the laser to lase fully. I'm sure this is temp related. When I picked it up it was on so I did not get to see how it starts up. I have contacted the MFG. about a manual and a spare tube. second pic shows arc in tube that did not go away after the laser came to temp at least I think came to temp.

Pics of the Projector side of things. Lower left is the DMX board for shutter..and color select. I'm going to work at cleaning up the wires / taped on stuff

MEGA!
I like a good CuBr

The power supply is mono phase for sure. I have a transformer that has tap points 105 110 115 120 . The current select tap is on 115 since I have 120 out of the wall I'm thinking I should move this down to the 120 spot see how that helps the heaters.

I love that yeller...

Copper vapor seems simple up front but the various plans and projects reveal it's not an easy thing to build. What does a tube like that run ($) anyway? Can't be too cheap.

I will be getting an extra tube as soon as I can get anyone at pulsLight to respond so I will let you know. My guess is going to be $1000-$1500 USD. It only has one mirror and the cavity does not look to complex. The tube in the laser I have here is at 956hours about 1000hours is max for them.

The magic is all in the power supply...

My temp controller is way off when I was running, it thought the tube temp was 430c but it should have been room temp 21c. The set temp is 415c so I'm not sure if it even kicked on the heater. So how it lased with out a good warm up I don't know. If the thermocouple is IEC color code it is a type K and I made sure the controller is set for that. If I put my fingers on the probe it does register on the controller...So it detects heat it would seem. I guess I will attempt to order another probe. Since I know of no way to test if its the controller or the probe.

Here is a shot inside of the inside of the tube and you can see some copper has recrystallized?

Welcome to the CuBr land. Keep in mind that CuBr lasers are pulsed and especially hazardous. I'd love to compare notes on your model. I've got a Spectronika and have a sneaking suspicion that the pulselight 'borrowed' a lot of their design from Spectronika. I don't think you're going to have much luck getting a hold of pulslight as they're out of business (as is Spectronika).
