Re: [TCML] Off topic? Inductively-coupled N2 laser
N lasers, at least the free air TEA sort are nanosecond lasers with a single
light pulse and no mirrors. The spark gap and capacitor need to be able to
handle this and "frequency" must be heading up to 1GHz.
RF exitation for CO2 lasers is of the 100MHz region. I have a 350W laser
without the driver. None of this is in TC territory for RF excitation.
Lower current current limited supplies may be fine for electrode designs for
CO2, HeNe etc

I don't see why it would not work, quite a good idea actually, as the only
real use for the HV power supply in lasers is to ionize the gas. The type of
gas and alignment/distance between of the mirrors controls the rest. But
typically the power supplies are lower voltage higher current. such as a
neon transformer. I have heard of 12/60's being used for 1meter Co2 lasers
before.

Hi. Im an amateur coiler and happen to use a NTC 6axis laser for metal work.
As far as i can gather the basics for its operation is high voltage being
pulsed through a tube filled with a gas mixture reflected off several
mirrors and focused through a lense. I believe the output is the same as a
TC just at ultra high frequencies. So i dont know if you can really "use" a
TC as a component for a laser or if a laser is basically just a TC with a
different looking streamer.
Im helping :)

Dear List,
With possible interest to coilers who are also into lasers I have noted
some Russian research into inductively-pumped gas lasers, in relation to
possible relation to tesla coils especially direct-coupled LC networks of
the type mentioned previously on the List by ACMQ:

Is it possible to, use a TC to pump a laser i.e. by using a "lasing" gas
e.g nitrogen to fill the inside the form of the secondary and with say, a
mirror at one end of the a window at the other to allow the laser light to
exit, the high voltage across initiating the discharge and the magnetic
field sustaining it until the capacitors were discharged, the cycle then
repaeting. Would it likely be a good opportunity for the amateur
experimenter to make say a decent Nitrogen laser or is likely to be very
challenging?
