I've had a 50mW pen from FP, but I was very disappointed with its performance. It did output good power for ~1sec, then hopped to TEM01 and power decreased to less than half. Here is the link: http://www.focalprice.com/detail_LP098S.html It looked like exactly like the pens SkyLasers sell...

Thank you all for the warm welcome! It's great to be here. I forgot to mention that I'm not native English speaker so you may find my English somewhat bad. Anyway I received an offer for a lathe from a liquidating factory. Only $350. Apart from the fact it uses 3-phase 380V mains, there is...

I have one of these modules. A 100mW one. It's a pretty decent module for the price. Some data: Current - 560mA at a voltage from 2,7V to 3,4V. Pretty stable. Beam diameter at exit is 2mm At 5 meters it is 5mm (0,6mRad divergence) Diode is definitely 9mm. Its leads are very thick. Power is very...

Here is my relatively small, but steadily growing laser collection: From left to right: 1. My first laser. 1mW red if I remember correctly. It's 10+ years old and still works. 2. 5mW red from DX. 3. Does it need a description? 4. GBW-H10N 4x Blu-Ray in focusable host. Set at 160mA. 5...

OK, not exactly new. I've been lurking here for few months but yesterday registered, and this is my first post. A little about me: I'm a 18 (almost 19) year old university student of computer technology. My interest in this hobby started after reading an article about lasers (to be more...
