In this paper, the threshold value of stimulated Brillouin scattering (SBS) was measured over the temperature range of 10-45℃ in liquid water. The experimental results indicate that influence of temperature on the threshold value of SBS is very distinct. The threshold value of SBS decreases with the increase of temperature. On the basis of theory and experiment, the physical mechanism of the temperature...
We demonstrated CW current injection of GaN VCSELs with hybrid mirrors at room temperature. The laser characteristics, such as temperature dependent laser threshold current, spontaneous emission coupling factors, have been measured and discussed.
We successfully fabricated and measured the GaN vertical cavity surface emitting lasers with hybrid mirrors at room temperature by CW current injection. The lasing wavelength was located at 412nm with a linewidth of 0.5 nm. The threshold current was at 9mA.
Using the Z-scan technique, we verify the threshold energy for a 19 ps laser to induce outward solute migration decreases with the increase of the solution temperature, well agreeing with our proposed potential well model.
