combining multiple beams in a portable laser is a tall order (albeit not impossible by any means). the question is, why would you want to when people are pushing these diodes to 2Ws?:thinking:

probably smart to learn to do that, if you get into Hv lasers like bare tube HeNe and ssy-1s.:crackup:

electricity like to follow the path of least resistance, theres no reason for it to go to your heart (if you need to go to phoenix, why would you stop by New York first?). also, with your internal body resistance, if the electricity were to get to your heart, it would only be about 40mA.

Silicon wire I know there have been concerns about the thickness of the insulation of Mohrenberg's silicon wire, I thought I might tests the concerns as well as the claims of Mohrenberg. first, is the wire flexible? yes... is the wire heat resistant? conductors are red hot from the...

cni is on Holiday until the 6th, the order will hopefully be finalized shortly after.

realista, the endeavor is a GLP and the group buy prices are significantly cheaper than nova. Glenn, any updates would be nice.

sorry, been a crazy week. anselm: the tube is powered bluefan: James1095: the beams are combined with dichros, the mirrors on the HeNe reflect red and pass blue. turning down the argon would not make white, the dichros on the HeNe reflect a large portion of the green lines. after passing...

i was playing around with my gas lasers today, i decided to shine my argon through my little HeNe tube. here's what i got:

i think if cni were making 515nm PENS then it would have showed up on their website before amazon... my 2 cents... Edit: wrong thread i have two tabs next to each other, both start with "510nm". why do you do this to me Trevor?:na:

here's my tutorial. http://laserpointerforums.com/f45/laser-cut-laser-tutorial-image-heavy-63532.html#post907433

i didn't take many pictures while making this, so my tutorial consists of many the design phase. i thought it would be easier to show the design steps visually. now you wand to copy the main support structure over and add the hole which will be the size needed for the part it is...

808 does not get absorbed as effectively by your hand than the lower wavelength lasers. nice review!

the front lens was knocked out of its place and the acrylic stand Xplorer made for the driver had a huge crack in it.

its actually incredibly likely to be alignment that is giving me problems. this is the same laser in the OP but it took some HARD hits in shipping.

No, the LED doesn't turn off. I cant speak for thermal stability because the TECs could be broken and i don't want to re-align the diode/crystals. However, the beam is not being blocked, feedback is hooked up and the laser is mostly not on fire.

hey, i seem to be getting about 2mW out of mine. also, it never stabilizes. any suggestions?

sorry, i missed the part in the rules where it had to be started by the start date. this project (while it hasn't been discussed here before) was done before the competition. sorry,

i might as well enter this. while waiting for parts for my PGL, i decided to make a host for the 75mW green module. i sat down in front of a computer, opened up corel, and designed the host. i then cut it out on a 50W co2 laser cutter. after that, i spent a few weeks tweaking the host and making...

The noise reduction works great! I will play with it more tomorrow. Thanks Trevor.

i cant wait to get that GLP-589nm-0.6-1mW. thanks Glenn!
