Just to close this subject, the problem was the laser required a bit more than its regular 11mA current to keep stable.
Lasos GmbH was very kind to provide me with their engineers support to confirm 142laser's diagnosis
unfortunately the standard power supply for this laser cannot have a variable current and is fixed to 11mA.
I finally ordered a laser from a very hard to find Ukrainian company, which I hope will work sweetly !
RIP Ukrainian laser, today more or less 1 year after the first setup it appears to have died.
Symptoms are : at start-up it lases for a few seconds then it fades down to just residual blueish glow out of cavity/Brewster. ( tube still emits yellow-orange lateral light )
I would believe it’s more a problem with the power source which fails to « keep the pace », maybe because tube somehow aged meanwhile. Any suggestions of how to troubleshoot this little monster
?
