what if you get caught slipping some other guy a love letter, then you would look really... you know! Backfires big time :-/ [edit] I didnt read the post before mine, looks like phoenix had the same idea

Re: Whats the worst you have evr been shocked I stepped on a HeNe power supply while only wearing socks. i had bare wires laying on the carpet and some of the insulation stripped back with copper just wrapped around the Alden connector... the lights were out in the room at the time.

just like in the thread "good free video file convertor". what are some good video editing programs???

I must admit, This application is very complicated and has a lot of options! its very nice but im having trouble with selecting a working audio encoder. i can convert a video but i don't get any sound.

Awsome! what if you drop it though? is it insanely fragile?

Does anyone know of a link that shows or explains the geometry of the crystalline structure? and how critical is the entrance angle?

I like that link, Thank you! ;)

Okay i just saw an interesting sentence in the Handbook of Laser Technology and Applications V.III which states: "the two-photon process is a nonlinear process, the absorption and fluorescence depends on the square of the infrared light intensity" Im not 100% sure they are even talking about...

I don't mean to be rude but I would tend to believe that is incorrect just for one reason, if that were true then i would imagine you could just pump the KTP as the lasing medium.

I just did a little research and realised that my simple way of looking at it is incorrect, The output photon is a combination of two input photons. so there is a gain in power if measuring individual photons but no gain in power if measuring the whole emission. Still, how does a crystal...

How do Potassium Titanyle Phosphate crystals double the energy of photons? It confuses me when i think about it in its simplest form = a single 1.16ev (1064nm) photon enters the crystal. a single 2.33ev (532nm) photon exits the crystal. How did that photon change to a higher energy state...

Yes and no, the number of other factors involved is just too much to make any accurate assumptions at this point. As you said, "we've cut back and strived for more efficient vehicles and alternative fuel vehicles". This means that more people now have vehicles that use less fuel which lowers...

I know so many people who sold their big gas guzzlers for dirt when they heard >$5/gal was around the corner. Man where they wrong!!! Im glad i didnt sell my boat!!! shes gonna be worth quite a bit come spring  ;D

Ahahah, you should have told me that when I designed my "Boom Tubes"!!! Three 3 foot long 2 inch diameter sprinkler pipe with the bottom end capped and top open, a little hole in the bottom, and oxy acetyl welder to fill the tubes with gas and a propane torch to flare into the fill hole. Wicked...

Re: Hows this for a side business (Re-gassing lase What’s your application? And when you're talking custom chamber you are talking big money! Your best bet is to find some old research chamber that someone is selling. But the easiest way I can think to make a DIY chamber is to get a spool...

how many sleds?

Re: Hows this for a side business (Re-gassing lase low threes can easily be achieved using a two stage rotary vane pump with very clean oil (I use Fisherbrand 19 or Welch DuoSeal). If i need a deep vacuum i will run my pumps till they are hot, drain them, flush them and fill them with fresh...

Re: So lets talk gas laser business Heres a video that shows my Fisher Scientific rotary vane pump roughing down my Varian turbo v70 UHV pump. you can also see one of my convectron gauge tubes and the digital pressure readout along with a bunch of reducers, flexible bellows, valves and fitting...

For many years I have been into vacuum technologies. And over these years I have collected some rather useful tools. My most highly cherished possessions are my vacuum pumps. I have two UHV turbo pumps and a few two-stage oil lubricated rotary vane pumps. My second most cherished are my vacuum...
