Limitations on measuring solvent motion with ultrafast transient hole burning

Tai Jong Kang, Jongwan Yu, Mark A. Berg

A number of limitations to hole burning in the liquid phase are identified. As spectral diffusion becomes more rapid, a point is reached where the narrowest hole width no longer measures the homogeneous linewidth. Spectral congestion of the solute is also shown to limit the fastest detectable spectral diffusion rate. An optimal pulse length is found which allows observation of the most rapid spectral diffusion. In addition, the coherence effect observed when the pulses overlap is shown to have resonances at both the excited and ground state vibrational spacings. The coherence effect greatly resembles the hole burning spectrum, but contains no dynamical information. Because of these limitations, hole burning may not be observed even when the homogeneous spectrum is well resolved and spectral diffusion is slow. Experimental confirmation is found in the hole burning spectrum of iodine in hexane, which shows no hole burning despite having a narrow homogeneous linewidth.A number of limitations to hole burning in the liquid phase are identified.

Laser frequency stabilization using regenerative spectral hole burning

Peter B. Sellin, Nick Strickland, Thomas Böttger +2 more

Summary form only given. We introduce laser frequency stabilization using continuously regenerated transient spectral holes in an inhomogeneously broadened resonance of a solid. Narrow spectral holes provide extreme frequency stabilization for time scales appropriate for spectroscopy, signal processing, laser ranging, and interferometry. This technique thus will have significant applications beyond the field of spectral hole burning.

Research of hole width and depth on laser duration in spectral hole burning

Quan Shan

With the transient solutions of optical Bloch equation the dependences of hole width and depth on the burning pulse duration have been discussed in spectral hole burning of two level system.With a strong and short π pulse ,a deep hole can be burnt mode which width is much narrower than the steady state one predicted by optical bloch equation safficient.
