SSY 1's Recently?

Also, does anyone know the decimals for the wavelength output of Nd:YAG? Like 1064.___nm? Or is there a range like diode lasers?

None of the online sources I can find gives anything more specific than 1064nm. Why would you even
need to know such a thing?

The emission is always at the same wavelength. It does not vary like a diode laser.
 
Hwang ---
I see you have more questions ------------
What is your project which needs to be within +/- 0.999 nM of 1064 nM ???????
I believe that one of my new lasers is 1063.849 nM based on visual observations.
That is good because 1064.382 nM would likely shatter my coated BK-7 glass lenses
by heat absorption due to the narrow bandwidth of the AR coatings. That's about
$90 worth of glass :-(
I have not yet turned up the power to try for air ionization until I know more about
the fine points of the device including wavelength.

Aww, yours is much shinier than mine. :( I hope it's shinier on the inside than it is on the
outside. After all, it's what's on the inside that counts.

I hope they didn't dislodge anything when they ground the number into it. Now if only I can
figure out weather it is an 86 or 98! :thinking:
 
LS --
Start with about 450 volts @ 15 J. The end with the "nipple" is the
output and that simple housing appears to have a close focus PCX
lens PLUS a "black" window to block visible light.
150 uFd of flash capacitor should get you started.
WEAR GOGGLES FOR 1064 !!!!!
Can you see through the cavity?

LS -
I just found this.......
You need a lens to burn stuff - the diffused
beam tends to be weak. I use a 125 mm PCX
lens coated for 1064 nM.

Thanks for the tip. :beer: This project had me digging through the box of camera flashes to
find just the right one. There is a model of disposable camera out there that is button
activated. It shuts itself off when the target voltage is reached. Unfortunately, I was unable to
locate that particular one, but this other one still works quite nicely. The one I was looking for
uses a special transistor with built-in bias resistors to sense the voltage on the capacitor. It's
very interesting and clever, but probably works off of a single AA and so isn't a good fit for an
18650 anyway.
 
LS -- Your camera flash may provide enough energy to make it lase. You need between 7 or 8 Joules to start. Your flash has a trigger circuit but the "SSY-2" has its own trigger circuit on the side. I don't know how or if you got the tube to flash.

What voltage and mFd did you apply to the tube?

Yeah, it's a bit difficult to tell from the video, but it was indeed flashing and did seem to be lasing a bit.

The original SSY-2 trigger was used unmodified, piggybacking from the trigger cap on the flash board. The
entire ensemble was all about minimal modification. All I did was strip wires and attach alligator clips. :D

Input was 10.89J (200µF, 330V), charged from a single 18650
 
I'm new to this forum so please excuse indiscretions. I have an interest in the SSY-1 as I have been using one for about a year in my LIBS spectrometer. This contraption has been so successful that I am concerned that I might need a backup laser and the SSY1 seems to have dissapeared, at least I haven't seen one since I bought mine. I am considering the so-called SSY-2 but Hemlock Mike tells me that it only puts out about 7.5 mj. If anyone has pushed it further please let me know. A couple of points of info: Hwwang21 in post #5 asked "what does SSY-1 Mean" I believe the answer is nothing. I believe that it came from the fact that some of the units were marked with the FSC (Federal Stock Class) (now NATO Stock Number) and the part number.
19207ASSY12272885 all run together just like that. Most likely parts of the marking were obliterated and only the middle part remained giving us the "SSY!" Also Peter Krogen on his website has an email from a guy who worked on the development project says"I have seen the SSY-1 designation before and really do not know where it came from. I do not believe any of our liceneese used that designation."
Hemlock Mike I'll bet you meant barium sulfate rather than barium oxide. Barium sulfate is widely used for its high reflectance across a wide bandwidth while barium oxide is quite toxic and hygroscopic.
I am guessing that a lot of folks have removed the q-switches from their SSY-1s to get more power. I might be interested as long as they are in good condition.
 
John --- You are correct --- It is Sulfate. It has been soooo long
since I coated a cavity. I'm careful with Beryllium Oxide too!
The SSY-1 has a larger flash tube to take 11 Joules. Business has
delayed the realignment of my "SSY-2" unit with it's new tube.
The YAG rod in both units are about the same size but the Q switches
remain an unknown. The front output "nipple" has a diverging lens
and an IR pass filter to block visible light for war purposes.
You may ask Part2Go if they have a working 10+ mJ laser... Might
cost a few $$ !!
I used to be an engineer at Sperry / Unisys building those dinasawers
you speak of. I called them by that term once and almost got fired!!!!

Thanks for the flattering remark Mike but I am above no one. I just want badly to be able to know "What's it made of" so I've spent a year studying the subject. BTW to anyone interested there are a few new SSY1s out there but they're over $500. Don't remember where but I can look it up.
