Hello,

I managed to find out how to increase power for sd303, by the harder way.
Now i can't put crystal on wright position.

To get more power simply drill 2 mm hole on the position in picture below, to access potentiometer.

Warning! When boosted, electronic component, specially big resistor will heat a lot. Do not use it more than 10-15 second at once.

Sorry for my grammatical mistakes.

My 303 changes TEM modes too! It arrived today. First, when I push the button, the dot is TEM00, then quickly switch to TEM01 (two beams), if I turn it of and on again, the beam comes from TEM00 to TEM?? (I only seen a rectangular shape), If I heat it with my hands and turn it on, It goes to TEM00, but sometimes goes to TEM01, so, with lower output power!

Very sad! I don't recommend!

Yeah try looking at the date before posting. I just read through the whole lot before realising it had been posted in 2011. :gun:

FYI I did a new review of a very similar laser (from Aurabuy) here, its labelled as 301 not 303, but it has the same output claims and build. Its quite stable in TEM00 and doesnt mode hop. :beer:

Can someone help me, I bought the sdlaser 303 today and I plugged battery in and It got charged then I put it back in. My laser didnt work, so I opened it up and there is like a really tiny red dot (I don't know why it has a red dot when its a green laser) so anyone :D?

Dropping it could have messed up the crystals. It could have happened in production or shipping.
