Finally, after 5 years of searching in my country I found my first Helium Neon LASER!
LASER head model Melles Griot 05-LHP-401, and high voltage power supply is Power Technology Inc. model N017-1111 Its labeled 1365VDC and 5mA
I buyed relatively cheap, about 15 USD laser + 15 USD high voltage power supply, and it work, but beam was very weak. I had a meeting with my local institute for physics, I asked them if could measure power of my laser.
Power was 50 uW (microwatts) :undecided:
I was disapointed, but the professor reminds me that at least I have working and stable high voltage power supply I got very very cheap.
I put a couple of pictures, beam on wall 20 feet from laser with, and without camera flash (I am impressed of beam brightness only 50 uW)
And that is, my first Helium neon LASER!
Now I am looking for another one at least 5mW I hope to find.
