Area of Science:

• Solid-state spectroscopy
• Quantum optics
• Materials science

Background:

• Thulium-doped materials are investigated for optical applications.
• Understanding optical dephasing is crucial for developing new technologies.

Purpose of the Study:

• To measure optical dephasing in Tm(3+):Y2Si2O7.
• To evaluate its suitability for time-domain signal processing and data storage.

Main Methods:

• Photon echo measurements were performed.
• Optical dephasing was studied as a function of temperature and laser excitation intensity.

Main Results:

• A coherence time of T(2) = 23 micros was measured at 1.24 K for the (3)H(6)(1) ? (3)H(4)(1) transition.
• A homogeneous linewidth of 14 kHz and an inhomogeneous linewidth of 100 GHz were determined.
• An inhomogeneous-to-homogeneous linewidth ratio of 7 x 10(6) was calculated.

Conclusions:

• Tm(3+):Y2Si2O7 exhibits favorable optical properties for advanced applications.
• The material's large linewidth ratio and suitable transition wavelength make it a promising candidate for time-domain signal processing.
• Its properties suggest potential for transient optically addressed data storage.
