Yep, Pumping a laser with RF is basically magic. RF takes all the fundamental principles of DC circuits and throws it off the cliff. Millimeter lengths of wire or a speck on a solder joint will make or break the gas ionization thus killing any chance of lasing.

Also, both LED's are lit on your driver board so you should be getting an output from it. You can use a CB power/SWR meter to verify you should be getting about 35W of RF to the FET.

Yeah, definitely need a fuse on the FET filter board. I think it's a 10A if I remember correctly. I need to see what's going on on the FET side of your HS. Looks like your missing the choke coil needed for it to oscillate correctly. This is the hardest coil to adjust to get it to lase. Also the...

Agreed, However, I care more about longevity. Most of the arrays I build run each 445nm diode around 750mW. I'd rather have a product that will run cool and stable for years versus max output for hours. Lightshow projectors have a very different duty cycle compared to a pointer. Output...

Re: WANTED: 5 Projectors ASAP Hi, Thanks for your PM. Looks like Dave got it for me. Thanks Dave! ;) Anyway, Best price I found so far is $725. I was quoted $650 a while back so I'm looking to get as close to that number as possible. Do the A230's have the same diode arrays in them as the...

Eh, I'm okay. I just take a while. :san: Got it, Thanks for the lead. I'll PM him. Yeah, I messed up on my original post. Can't seem to edit the title for some reason so if a moderator could change it to read "Ca$!0", that would be great.

As the title says, I need 5 Ca$!0 projectors,,, yes, with the diode arrays. 130's or 140's new or slightly used. I can paypal the funds. If anyone has 5 to sell or knows a good source for cheap units, let me know. Thanks, Adam

Hey guys, I have this He-Cd laser on ebay and figured one of you guys would be interested in buying it to make a CO2 laser housing out of it. Check it out... Omnichrome 456 He-Cd Laser with PS - CO2 Case - NICE! - eBay (item 290430056112 end time May-28-10 18:07:10 PDT) Oh, I have some other...

What the hell is a milliwatt! :p:p:p:p Oh come on!, The fun doesn't begin until you break at least 10W!!! :eg: :san: Yeah, Not cheap but sure is fun to play with. :drool: Oh, and eye protection is a MUST! These IR regions are deceivingly EVIL. Size does count! I'm 6'2". This CV laser is...

Hey Jerry! On the contrary, I think your post was more than appropriate. After I posted my "First Post" here on LPF I realized, "Yikes! this is my first post!?!? Boy, that's not going to go over well..." I could have swore I posted here before but I guess I didn't. Your post helped me open up a...

Hey Jerry! Thanks for your concern. I agree, I just looked at my number of posts on LPF and was shocked to find this was my first! :D Well, In my defense. I'm a fairly well known member on Photonlexicon and have had MANY dealings with people over there. In fact, some of these members are also...

For all of your mad science needs!!! 60 Watt IR Burning Laser Diode With Driver and Chiller! - eBay (item 290421039813 end time May-02-10 14:34:44 PDT) I will also consider trades. I'm looking for 1.5-3W 532nm DPSS laser module. Viasho or LaserWave.
