Abstract:

We report a noncollinear (NCL), high-power, synchronously pumped femtosecond optical parametric oscillator (OPO) based on type I (o → e + e) phase-matching (PM) inside the yz optical plane of BiB₃O₆ (BiBO) crystal. By the application of NCL PM geometry for the parametric interaction, two important goals have been achieved: 1) simplifying the wavelength tuning by transferring the full tunability (620-1030 nm for signal and 1030-3050 nm for idler) from two optical planes (xz and yz) of the biaxial BiBO crystal in the collinear PM geometry, to only one optical plane of yz, and 2) considerable shortening of the produced signal pulses (down to 33 fs at 670 nm) across the tuning range.

Deactivation Processes: Jablonski Diagram

2.3K

Luminescence, the emission of light by a substance that has absorbed energy, is a process that involves the interaction of molecules with light. The energy-level diagram, or Jablonski diagram, is a graphical representation of these interactions, illustrating the various states and transitions a molecule can undergo. In a typical Jablonski diagram, the lowest horizontal line represents the ground-state energy of the molecule, which is usually a singlet state. This state represents the energies...

Photoluminescence: Applications

1.3K

Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...
