Hydrogen Laser

The chirping pulse of a laser has revolutionized everything we imagine as a laser today - with electricity. Britain has teamed up with Germany, France, and the United States to study the possibility of producing clean energy by firing a huge number of powerful lasers at hydrogen balls. The invention refers to a hydrogen fluoride laser that can pulsate chemical gases to create a high energy, cost-effective, high energy source. [Sources: 6, 7, 8]

A fully functioning laser fusion plant would need to consume up to 10 hydrogen pellets per second to ignite the laser field simultaneously. Hydrogen lasers can be used to access a range of energy sources such as solar, wind and hydropower, but the supply requires hydrogen gas if an effective reduction is carried out, possibly with just one laser beam. A near or IR high-power laser is about ten times more powerful than a conventional laser and requires about 1,000 times more energy. It requires the same amount of hydrogen as a normal laser, or about 2.5 times as much energy as a typical laser. [Sources: 2, 3, 4, 7]

Helium - Neon lasers are often used for alignment interferometers and compete with laser diodes that are more compact and efficient. Similarly, ion lasers were often used to pump out titanium and sapphire lasers, and are now often replaced by solid-state lasers that double their frequency. One of the advantages of using certain gas lasers, such as helium and neon, is that they offer special wavelengths that are otherwise difficult to obtain and can be used in a wide range of applications, from high-power laser systems to medical imaging.

Another interesting aspect is the relatively high optical power that can be achieved with gas lasers. Compared to a diode pumped out, the price depends on the power required and the size of the device. Following technological advances in the lifetime of the devices, a CO laser with an emission of 5.5 mm could be available in the near future as a cost-effective alternative to conventional laser diodes. Compared to widely used CO lasers, helium neon lasers offer significantly lower costs and a longer service life than conventional lasers. [Sources: 3]

In addition, a reduction reaction can be generated by a laser pumped out with sunlight, which can cause a reduction in the wavelength of the laser. Moreover, light emitted by a diode or semiconductor laser and producing wavelengths corresponding to laser wavelengths may be used to trigger laser vibrations accordingly, as in this present invention. [Sources: 2]

A good example of this aspect is the carbon dioxide laser, which is a laser with a wavelength of about 1.5 micrometers and a power of one kilowatt hour. Due to this improved property, it is also possible that a detector material reacts more sensitively to the wavelengths normally emitted by the hydrogen fluoride laser. Since direct suction from a vacuum pump is also undesirable, the hydrogen fluoride produced in the laser can be trapped in sodium or similar materials. [Sources: 3, 8]

An interesting question with lasers is not only whether the components can be processed, but also how the laser beam can be brought into the workpiece. To make the transmitting laser beams more efficient and reliable, the first thing that comes to mind is a beautiful long hydrogen bath. Hydrogen absorbs the photons of a laser at just the right frequency, and this frequency contains valuable information about the atoms. Such minute control is important when working with a large number of components, such as a hydrogen fluoride laser or a carbon dioxide laser. [Sources: 0, 1, 5]

Hydrogen is previously produced by electrolysis, charged by high-pressure vessels and then transported to various locations for use. This process causes the hydrogen atoms to fuse into helium, the same reaction as hydrogen bombs and stars like the sun, but in a controlled reaction. The use of helium increases the properties of a hydrogen fluoride laser, as it turns out that helium does not change them favorably. Hydrogen fluoride lasers work with the device shown in the illustration. [Sources: 2, 7, 8]

The laser fires a pulse of 500 terawatts of power onto a 1 mm long deuterium pellet, which is found in heavy water. Helium cadmium lasers are more like helium neon lasers, but the average output power can exceed 100W. They emit a high amount of light, about 1,000 times stronger than a neon laser, and can fire pulses of up to 1 terawatt power. [Sources: 3, 7]

According to the present invention, a pulsed hydrogen fluoride laser can provide an initial pulse that can be repeated hundreds of times per second. Although the data demonstrate the feasibility of chemical hydrogen fluoride lasers for most of the above applications, the output pulses are insufficient in terms of power and duration. [Sources: 8]

Most excimer lasers are ultraviolet lasers, but they work with current pulses that emit intense nanosecond pulses. At the moment, pulsed hydrogen fluoride lasers seem to be suitable for stimulating laser amplifiers and for measuring the increase and relaxation in various gases. [Sources: 3, 8]
