A 70,000-D membrane protein (MP70), which is restricted to the eye lens fibers and is present in immunologically homologous form in many vertebrate species, has been identified. By use of anti-MP70 monoclonal antibodies for immunofluorescence microscopy and electron microscopy, this polypeptide was localized in lens membrane junctional domains. Both immunofluorescence microscopy and SDS PAGE re...

Measurements of two-photon-excited fluorescence (TPF) of fluorescein and Rhodamine 6G in various solvents were performed with a continuous-wave (cw) laser for excitation and an acousto-optic tunable filter for spectral dispersion. Interestingly, the cw laser excitation produced an unwanted thermal-lens effect when the measurements were performed in solvents that absorb the excitation laser ligh...

In high power solid-state-laser systems, one of the major problems is the thermal effect, which occurs in optically pumped laser materials. Heating of the laser medium causes thermal distortions, leading to degradation of beam quality. The main thermal effects in laser rods are thermally induced birefringence and thermal lensing effects. High efficiency, high power and good output beam quality ...

Transient lens (TL) spectroscopy was developed with sub-micrometer spatial resolution to observe the temporal and special behavior of the nonradiative processes of carrier dynamics in InGaN/GaN quantum wells (QW). We have observed the carrier density dynamics and the thermal dynamics in the TL signals with a nanosecond pulsed laser. We have also observed TL and photoluminescence (PL) signals by...
