My 200mW was confirmed RIP just now, after 2 weeks of care and playing around discreetly :banghead:

Here is the case.
Since I know it performed best under low temperature 18~21 Celsius. So, I often chill it with my air-con before burning some stuffs with it. Just now, may be I had over chilled it, I press the button .... there is no lase at all~!

The indicator light was running but it just unable to lase. I was devastated and try a full charged battery. Still the same situation, only the indicator light is working and it can't lase. Tried dismantled the whole thing, the crystal was nice and clean, no burn marks or crack.

I guess, due to some extend of low temperature. The circuit unable to regulate the voltage efficiently and with sudden influx of high voltage. Indirectly it killed the diode or circuit.

Lesson learned: Never chill it too long and lase it, the cold shock will kill your laser diode. :tsk:

What an expensive lesson for a noob like me. It had costed me USD160 on this lesson. :(:(:banghead::(

Did you try to hold the button a little longer? It might take a while to get it to lase after being chilled.

No. It used to be just find, it fires immediately.

I did hold it long...but nothing happens. Is dead....:cryyy:

I will never buy high power Greenie again due to its highly unstable output.

It could have been using a crappy module and between that and the condensation left you with what you have now... Sorry to hear about that...

AC units don't usually put out air too much colder than 40-50F. If a pointer can't survive that, it's a piece of junk and was gonna die soon anyway. Condensation can't really happen on the inside of the module, since it's kindof sealed. Even if it did, condensation (distilled water) is not conductive unless it dissolves something first.

Sounds like a case of post hoc.

I think this was the quote:

"I can't help but think that you are the cause of this problem; we never had any problem with the furnace until you moved into the apartment." The manager of the apartment house, on no stated grounds other than the temporal priority of the new tenant's occupancy, has that the tenant's presence has some causal relationship to the furnace's becoming faulty.

You are right bro. It's my fault, can't blame anyone. This month wasn't great after all, whatever I approached it just turned bad eventually. My last few months was great to say.

Guess I need to pray more. Will make another saving, this time will target to get one from Jetlasers.

God bless and peace to all.

Whispering sweet nothings won't change your life. To do that you need to carefully guide your thoughts and behaviors. Create some goals and achieve them...
