Default Re: DX SD-303 200mW Review

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.

Default Re: DX SD-303 200mW Review

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!

Thanks for the info but look at the last date

Sorry 'bout your laser though - although I though dx stopped selling everything over 5mw except modules.

Default Re: DX SD-303 200mW Review

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

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.

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