Chromosphere population inversion?

In summary, the conversation discusses the possibility of using two mirrors, one half-silvered, in the chromosphere to create a resonant chamber and produce laser radiation. The speaker questions the feasibility of this idea and suggests that heat may be the source of excitation. They also note that this situation may already exist naturally in the chromosphere without the use of mirrors.

Assuming you could put two mirrors (one half-silvered) into the chromosphere, stationary, without them vaporizing/warping..., could they form a resonant chamber and produce laser radiation?

Interesting. Can you elaborate on what makes you think this is possible? What would you be stimulating to emit the light?

I would expect that the excitation happens via heat, in that case I would not expect a population inversion.

Another interesting thing: As a rough estimate, you can draw a straight line of ~3000km length through the chromosphere (nearly parallel to the surface of the sun). For the time-scale of 10ms and an area density of O(g/cm^2), you already have this situation without mirrors.
 

Related to Chromosphere population inversion?

1. What is a chromosphere population inversion?

A chromosphere population inversion is a phenomenon that occurs in the outer layer of the Sun's atmosphere, known as the chromosphere. It is characterized by a reversal in the normal pattern of temperature, where the upper layers of the chromosphere become hotter than the lower layers.

2. How does a chromosphere population inversion happen?

This phenomenon happens due to the interaction between the magnetic field and the plasma in the chromosphere. When the magnetic field lines become twisted and tangled, they can generate energy that heats up the plasma in the upper layers of the chromosphere, causing the temperature inversion.

3. What is the significance of a chromosphere population inversion?

A chromosphere population inversion is important because it plays a crucial role in the heating and dynamics of the Sun's atmosphere. It also has effects on the solar wind, which can impact Earth's magnetic field and cause auroras. Understanding this phenomenon can help us better understand the behavior of our Sun and its influence on our planet.

4. Can a chromosphere population inversion occur on other stars?

Yes, chromosphere population inversions have been observed on other stars as well. However, the exact mechanisms that cause them may differ from those on the Sun. Studying these phenomena on other stars can provide valuable insights into the magnetic and heating processes that occur in their atmospheres.

5. How do scientists study chromosphere population inversions?

Scientists use a variety of instruments and techniques to study chromosphere population inversions, including spectroscopy, imaging, and numerical simulations. These methods allow them to measure the temperature and emission of the chromosphere, as well as track changes over time. Additionally, spacecraft and ground-based telescopes are used to observe and analyze these phenomena in different regions of the solar atmosphere.
