Any object hit with sufficient power will start to ablate matter energitcally causing some thrust. It's too late for me to worry about it -- I was joking but that is a real question someone may answer. Think about one of those old radiometers in a vacuum bulb.

lol talking about old radiometers my RPL will make it spin very fast if you enlarge the spot if not i accidentally burned the coating off a little...... didn't know you could see smoke in a vacuum.

Nice fair review Diachi!

Recently I found out that expecting pure TEM00 output and full stability from a Chinese DPSS over 500mW is asking too much. The vast majority of Chinese manufaturers list ALL of their >500mW green DPSS lasers as being "near TEM00" which could mean anything.. I'm not trying to say that your unit should be unstable and drop to 100mW after a bit, but things get very different when you get into high-powered linear cavity lasers.

The spec sheat on WLs site specifys TEM00 though. This operates across about 5 different modes. TEM00 sometimes, TEM01 and TEM01* are the most frequent, then a micture of different modes happens too.

The spyder is good for shrinking heatshrink tubing though ;).
 
Getting the Chinese to post accurate specs is like pulling teeth. Given that your laser is listed as being 400mW, I think you have cause to tell Steve about it. While it is true that getting very high powers (600-700 mW and up) from a linear cavity DPSS and have TEM00 output and good power stability is pretty much impossible, they should be able to provide 400-500mW plus of stable power for that cost.
 
It's possible it was banged around in shipping. I'd also suggest shooting Steve an email.

That's not what is causing this. My unit was like this BEFORE being sent. According to the power graph supplied with it.

I've not had much time lately to contact steve or post back. I have a lot of school work and stuff with my band on atm. I'll try and find some time to actually remember to do it.
 
diachi, I know this is an old thread, but did you find there is no TEC in the Spyder III? (PM also sent) -Glenn
 
This laser is now in my possesion. Perhaps I could measure the power draw and depending on efficiency of the laser that should be able to give us an idea as to whether or not there is a TEC draingin the battery. I highly doubt it though as the battery life is pretty remarkable for the amount of power this thing is putting out.

Oh yeah I remember those, but me I'm talking about a situation where there's no vacuum.

Well with my 2MW pulsed YAG laser it is possible.
You can move like small pieces of charcoal.
The laser forms a plasma explosion on the surfac and that gives it the thrust.
 
I didn't know the host of the spyders was that big! Looks awesome... A bit silly about the mode hopping issue and the "continuous" duty cycle.. I wouldn't have believed it for a laser of that power from WL anyways :P
 
i know this is an old thread but a quick question. The poster stated a 3500$ price tag!!!!

back in 2008 was that a common price for a 500mW laser? Just curious and thank you for any responses.
 
Yes (especially at WL).

Prices have come down significantly since then

Peace,
dave
