Low-threshold lasers based on a high-mobility semiconducting polymer
(2006)Progress toward electrically driven conjugated polymer lasers should benefit from the identification of materials that exhibit good charge transport properties coupled with large optical gain. Here, we report a detailed ...

Single-Ended Infrared Photothermal Radiometric Measurement of Quantum Efficiency and Metastable Lifetime in Solid-State Laser Materials: The Case of Ruby (Cr3+: Al2O3)
(1993)A new, simple, and self-consistent frequency-scanned photothermal radiometric (PTR) detection scheme was applied to the measurement of the metastable state de-excitation parameters of a ruby laser rod. From the extrema of ...
