That was brilliant. Thank you. Does this mean that if the tube is a perfectly sealed unit, that it will continue to function, as the molecules at 'rest' will return to their original state? Edit: I say rest, but mean a redistribution of charge.

[@jimhinkle7245]

How in the world did someone figure all of this out??? I'm barely learning about my diode laser. WOW!!!!!

[@adammontgomery7980]

I imagine there is some threshold voltage to get electrons to accelerate fast enough to put N2 gas into it's meta state. Does anyone know? I always wondered if there is a constant decay rate for electron's to drop energy levels. If so, could you pulse the voltage at the same rate to get more of the population of molecules involved in lasing?

[@jmchez]

The power supplies for CO2 laers that I've seen are in the 20, 000 to 30,000 volt range.

[@vrookLearning]

To achieve lasing in a nitrogen laser, you need to excite nitrogen molecules to a metastable state using an electrical discharge. The specific threshold voltage required varies depending on factors like gas pressure and laser design. Metastable states in nitrogen molecules have a finite lifetime, and the rate of decay depends on energy level and molecular interactions. To maximize lasing efficiency, nitrogen lasers are often operated in a pulsed mode, where the electrical discharge is synchronized with the metastable state's decay rate. This ensures a significant population of excited molecules for lasing action. The pulse duration and repetition rate are crucial parameters in controlling nitrogen laser performance, but the exact values depend on the specific laser system and application.

[@adammontgomery7980]

@@vrookLearning thank you! It makes sense that the characteristics of the tube and density of gas make a huge difference on the voltage required to lase. Also good to hear that my intuition about pulse frequency was not totally wrong.

[@sheshankutty8552]

All theory is OK, does anyone make these in India ?

[@vrookLearning]

Yes, there are companies in India that manufacture CO2 lasers. Some of the companies that manufacture CO2 lasers in India are: Laser Science Services: They manufacture CO2 lasers for various applications such as cutting, welding, engraving, and marking. Prima Industries: They manufacture CO2 lasers for industrial cutting and welding applications. Mactron Technology: They manufacture CO2 lasers for cutting, marking, and engraving applications. Control Laser Corporation: They manufacture CO2 lasers for various industrial applications such as marking, cutting, and engraving. Laser Lab India: They manufacture CO2 lasers for a wide range of industrial applications including cutting, welding, marking, and engraving. There may be other companies as well, but these are some of the prominent ones that manufacture CO2 lasers in India.

[@ultimatebeyblader3026]

But, how is the laser beam taken out from that tube and used for various tasks?

[@vrookLearning]

As you see in the video, one end of the tube is partially reflective. So, it we take it out through that opening.
