Default omni 643 568nm Ar/Kr Laser , First light Temp

Hey ,

Well after a while of the head sitting on my floor as im currently looking for a PSU I decided to build a simple , very simple setup to test the tube and see if it works .

The circuit is from sams LaserFAQ and is intended for testing only .

The 568nm output looks green on the camera but is a yellow/green in person .

Tube current was 5A and a external 12V to control ignitor ( Opto isolated on the ignitor card )

Test under RF to see if gas was intact and 568nm photons from the HR end Brewster , There is also a blue light that passes though the HR , if I get a working PSU I would like to see if any other wavelengths can be seen with a external Ar/Kr OC and the current power as well .

more photos to follow : D

Same. I love 568... It's rather far more yellow than 561. Yet still green. It's very strange. Glad to see its gas intact afterall.

First time ive ever seen 568nm , looks like a green/yellow mix , Thanks .

Here are a few more shots of it running , last picture Is the bridge , caps , current monitor and the DC current limit ( 6A , Old air heater ) .

Are you direct driving the tube or are you using any of the head electronics at all? I'm amazed you got the printout mastered so easily.

Btw, put a bit of 532 or 514 in the frame and the 568 will show through more true.

Thanks , Ill try that soon : D

Pretty much directly , current is limited to 6A via heater element , its crude but works for testing , the only form of control im using in the head is the ignitor , it gets it voltage from the anode supply and doesn't need a boost supply , I plan to make a simple current regulator to run the tube happily for now till a find the proper PSU

When a voltage is applied to the anode , the ignitor keeps firing till a 12-15V supply is connected to pin 8/12 , that controls a opto and it stops firing .

im using 6 connections on the head , cathode 1 , cathode 22 , ignitor 8 / 12 , anode 6 and case earth

I got the pinouts mainly from google and tracing it from the RYB Omni I had that was dead .

Edit - Tried the external OC , managed to get the green 514 line by the looks of it , the HR on the tube leaks a lot of blue so I guess that wont lase .

Edit 2 - Well I replaced the mirrors as that was my original plan , Both the HR and OC are from the RYB I had , after some tweaking it lases on the yellow 568nm line and 2 blue lines . looks to be 488nm and something else . Stupidly made the mistake of moving the wrong screw and lost alignment so ill sit down and do it properly at some point . It did make a very a nice " White beam " though : D

I also measured voltages , the tube is dropping 156 Volts at 6 amps , heater is drop 144 Volts , Supply at caps is 300 Volts .

nice. I've been playing with the alignment on mine, and I still don't get any red. get tons of 568 and a few blues though....
