Realizing EIT with Pulsed Laser: Intensity, Duration & Frequency

In summary, the requirements for intensity, duration, and repetition frequency for EIT realized with pulsed laser will vary depending on the specific application and system. Generally, high intensity, short pulse duration, and low repetition frequency are recommended to ensure successful EIT. For further information, refer to Zoubi and Ritsch (2011), Xiao et al. (2016), and Passante and Persico (2018).

The exact requirements for intensity, duration, and repetition frequency for EIT realized with pulsed laser will depend on the specific application and the characteristics of the system you are using. Generally, the intensity should be high enough to ensure that the stimulated transition is saturated, the pulse duration should be short enough to ensure that the atom-field interaction is adiabatic, and the repetition frequency should be low enough to ensure that the effect of spontaneous emission is minimized.For more details, you can refer to the following references:1.

FAQ: Realizing EIT with Pulsed Laser: Intensity, Duration & Frequency

What is EIT and how is it realized with pulsed laser?

EIT stands for electromagnetically induced transparency, which is a phenomenon in which a medium becomes transparent to a certain frequency of light due to the presence of a strong laser. This can be realized by using a pulsed laser with specific intensity, duration, and frequency, which can manipulate the energy levels of the atoms in the medium to create transparency.

How does the intensity of the pulsed laser affect EIT?

The intensity of the pulsed laser plays a crucial role in realizing EIT. If the intensity is too low, the atoms in the medium will not be excited enough to create transparency. On the other hand, if the intensity is too high, it can cause unwanted effects such as ionization. Therefore, it is important to carefully control the intensity to achieve the desired EIT effect.

What is the ideal duration for a pulsed laser to realize EIT?

The duration of the pulsed laser also plays a significant role in EIT. The ideal duration depends on the specific medium and the desired EIT effect. Generally, a shorter duration is preferred as it allows for more precise control and reduces the chances of unwanted effects. However, the duration should be long enough to ensure that the atoms have enough time to respond to the laser.

How does the frequency of the pulsed laser affect EIT?

The frequency of the pulsed laser is another important factor in realizing EIT. The frequency should be carefully chosen to match the energy levels of the atoms in the medium. If the frequency is too far from the resonant frequency, the EIT effect will not be achieved. Additionally, the frequency can also affect the intensity and duration required for EIT.

What are the potential applications of realizing EIT with pulsed laser?

EIT has many potential applications in various fields such as quantum computing, optical switching, and atomic clocks. By using pulsed lasers, EIT can be achieved in a more controlled and precise manner, making it a valuable tool for these applications. Additionally, EIT can also be used for studying the properties of different materials and for creating new types of sensors.
