High power TEA laser Nitrogen v4,2, how to make

[nrz666]

So what's the power output?

[Alfonatr]

@nrz666 The output power is enough for laser dye coumarin, rhodamine 6G, rhodamineB and others without lens.

This laser was the best can I made, working with air I asume the output power is aproximate 2,4mJ with 0.8ns (200kW).

[nrz666]

@Alfonatr 200kW pulse? Sounds cool. Are there any ways to prolong the pulse a bit? Not a nanosecond but, for example, 20 or 100 ns. That would be more practical, I think.

[Alfonatr]

Isn't possible to long the pulse width, because depends of the gas pressure. At atmospheric pressure, the pulse width is 0,8ns, and is you increase the pressure obtain less width pulse.

For long pulses, at less pressure, about 8 Torr you obtain about 8ns pulse width (or more).

But the difference is the power ouput, not the energy.

For 160uJ at 0,8ns is 200kW (I was mistake the last energy, is about 160uJ), but at high presure and 0,2ns the same energy is 800kW.

[Alfonatr]

For a low pressure, the same energy 160uJ is 20kW , and with this power is hard for the dye laser.

wtf this isn't how to make one

[AnselmoFanZero]

He vaporizes the aluminum-coating of a CD with a 100% DIY laser!

Google tells you how to make one. Or just mail me if you want a TEA laser-kit.

[Alfonatr]

The power suply is easy, the input is at 12 volts and 5 Ampers. With a NE555 and two Mosfet IRFZ44, and one flyback of TV with internal diode.

@Alfonatr Could I just use the flyback?

Cool. What is the power supply for this laser ?
