Do you mean, removed from the spectrum of the pumping pulse due to absorption? This indeed might happen for a three-state laser, which of course constitute one of the disadvantages of this type of laser. However, pulsed laser, whose bandwidth may indeed be big enough to cover the laser transition, is not always used in most laser system, instead CW lasers enjoy more frequent use in pumping most laser systems.JG1009 said:During optical pumping in a laser, is the wavelength of light that corresponds to the transition from the metastable state that yields the laser light removed?
It depends which laser system you are talking about, if it's 2-level system then yes population inversion can never be realized.JG1009 said:Otherwise, wouldn't a population inversion not be possible as these photons from the optical pumping would cause stimulated emission immediately.
Optical pumping is a technique used to excite atoms or molecules in a specific energy state by using light. This is achieved by applying a strong laser light at a specific wavelength to induce a transition in the atoms or molecules, resulting in a population inversion.
The purpose of optical pumping is to create a population inversion, which is necessary for the operation of lasers. This technique is also used in various applications such as atomic clocks, nuclear magnetic resonance, and quantum computing.
Optical pumping plays a crucial role in determining the laser wavelength by inducing a population inversion in the atoms or molecules. The wavelength of the laser is determined by the energy difference between the excited state and the ground state of the atoms or molecules.
Yes, optical pumping can be used to change the laser wavelength by adjusting the energy difference between the excited state and the ground state of the atoms or molecules. This can be done by changing the intensity or frequency of the laser light used for optical pumping.
The laser wavelength in optical pumping is affected by various factors such as the energy levels of the atoms or molecules, the intensity and frequency of the laser light used, and the properties of the laser medium. Temperature and external magnetic or electric fields can also influence the laser wavelength.
