Laserscope Modification Just Finished!

[slicklasers]

I have a design right now which is capable of putting up to 2,000 Watts of 532nm light into a single beam with "good" beam quality, meaning comparable to the beam quality of the current version of the I-2000.

If you know anyone willing to buy the parts, I'll gladly build it! Figure a build cost somewhere in the low 7-figures for the 2kW version.

But what kind of mirrors can handle that power in that tight of a beam? wouldn't you need some sort of watercooled mirrors or something?

[DMills]

Water cooled mirrors are established technology for high power use (think CO2 cutting machines and the like), but the bigger problem might be the high per pulse energy (bulk liquid cooling does not help over 20 nanosecond time spans).

Solid state laser engineering has some numbers for damage threshold as a function of time, which I am not going to type out (several tables worth of data).

I would strongly suggest a pair of **high** OD glasses before even thinking about playing, seriously, these things are dangerous and even reflected light from the base plate is dangerous given the Q switched nature of the beast.

Incidentally, on the subject of laserscope kit, for the purposes of aligning the system, does anyone know if the OC from the dual wavelength IR option will serve as a lossy optic to control inter cavity power if fitted in place of the LAM HR mirror for alignment?
I have this mirror, I don't have the 98% one the alignment instructions call for!

Well I guess all that was aimed at me.

I guess not being a established member makes me an easy target !!


FYI, I am fully trained in laser safety and have loads of laser (including YAG) experience stretching many years.

Yes perhaps I am not as experienced as some of you but hey thats why most including of us are here...to learn and to help/exchange information with others.



Disspointed !

basically, dont do this:

[300EVIL]

...anyone with less experience than me with these types of lasers should not own one

Uh,,,Yes!

I'm really concerned with anyone who buys a laserscope for indoor show use. It only takes one slightly reflective surface to turn awesome into nightmare. Pulsed lasers are EVIL. I'm not saying it can't be implemented correctly but who wants to take the chance of a misplaced beam with the possibility of a faulty galvo. It only takes a couple nanoseconds to cause eye damage. No safety device built into the laser can prevent that.

That's my opinion.

Why not just run the laser CW for indoor use? 10W indoor should still be quite awesome.

Laserman532 is your man, he knows his shit see if he has the optic you need but be sure you have LOTS of money because it talks....

Laserscope systems are no joke and watching these prices drop so fast is scary !!! These systems are way dangerous !!! I remember the first system I had and letting it run through its self check , It jumped power to 40 watts and it scared the living shit out of me !!! From that point I realized instantly what industrial Laser power was all about ! Ive never had my laserscopes with scanners or done any kind of shows but relizing how f@#king Dangerouse these lasers are I dont know if I could do a show without woundering what would happen if a scanner failed . Anyway if your a kid that wants one , dont do it , spend your money on rgb. Its more colorfull !!

It gets even more fun when after about 20 minutes in test mode, with the medical computer, but some times as few as 10, it jumps from benign CW/low lamp to full RF and Full Lamp..

Just because you know how to hold down the right buttons during powerup, or push the right button on the motherboard does not mean the software is a stable....

It suprised the hell out of me the last time I worked on one.

Yup !! You know exactly what Im talking about !!! I had the beam terminated to a brick wall six feet away , when BAMMM !!!!!!!!! It lit the whole room up like a green bolt of lightning !!!!!!! I turned the unit off , turned the breakers off and went and sat down to watch tv , because I was scared to death of it !!! New respect for lasers that moment on !! It was the ''Laserscope wake up call'' !!!

I don't know what the R/T ratio of the IR OC is. But, I found that the regular HR mirrors are sufficiently transmissive (I guess about 0.1%) to do the alignment without changing any mirrors at all! If your thermal head type power meter isn't sensitive enough, you can use a photodiode type power meter.

Same here. There's plenty of IR leaking out to measure with a Coherent 210 meter.
