My new argon laser - first run

I have some problem with the JDSU power supply, current regulation doesn't work and there is always max at the output. This is why I used heaters (that glowing red sicks) as a ballast to limit the tube current to 6,5A. Stickers says the max power is 160mW @ 450-515nm but the tube is old and worn out.
PROBLEM IS SOLVED, the PSU works great :)

THE PROBLEM IS SOLVED! :D I took the PSU apart and then put it back together, since then it works great :P

Co to to czerwone ? :D Kwarcowe rezystory czy jakoś tak ?

[c4r0hv]

Napisałem niżej :) To są grzałki od grilla z mikrofalówki, czyli rezystory. Połączone równolegle dają 15 ohm / 2kW.

Hmm :D no ok ale nie widziałem w innych mikrofalówkach takich śmiesznych grzałek :D Widziałeś projekty z magnetronem zasilanym z 250W ? :D

Ja teżtylko w jednej na takie trafiłem. Po prostu spirala z drutu oporowego jest w szklanej rurce zamiast w metalowej z izolacją ceglaną. Z tym magnetronem to chodzi Ci o filmiki Danyka?

[Slu1982]

Tak właśnie :P Nie korciło Cię nigdy żeby to zrobić ? Masz dwa konta na YT ?

[c4r0hv]

Kiedyś trochę mnie korciło ale mi przeszło. Może kiedyś się za to wezmę. Tak, mam dwa konta.

Glad to see you got it fixed, and welcome to LPF :)

Now it's running at 6,5A, I'm planning to put 10-12A on it but I have to figure out what's wrong with the PSU first. There's also some kind of power sensor inside the laser head so maybe I will figure out what's the calibration of it (how many volts per watt) and then measure the power. After all, the laser arrived yesterday and I made it to work in one evening so it's very good result in my opinion! :D

Yes, those are heaters from microwave oven's grill :) Each 25 ohm 500W connected in parallel. I have no idea what's the output power because I don't have a power meter. Rated max power was 160mW when it was new but I don't know at what tube current.
