We report on thermal analysis and a continuous wave (CW) laser operation at (1.998µm) of end pumped Tm: YAP cylindrical laser rod. The Tm: YAP laser rod is pumped at a wavelength of 1.064 µm emitting from Nd: YAG laser source. A 3W incident pump power is used to generate a maximum laser output of 700 mW, representing 18% slope efficiency. The power of thermally induced lens in Tm:YAP laser rod is numerically analyzed and validated experimentally. The focal lengths of the thermally induced lens are directly measured using Shack-Hartmann wavefront sensor. We have detected blue up-conversion fluorescence emission before laser operation at 1.998 µm. The obtained experimental results were in good agreement with the numerical calculations.

Показана возможность синтеза соединений Cu2SnS3 и Cu2SnSe3 на стеклянных подложках путём отжига в парах халькогена тонкой металлической плёнки сплава Cu:Sn = 2:1 в вакуумной графитовой камере типа квазизамкнутого объёма. Методом рентгеновской дифракции установлено, что полученные плёнки халькогенидов имеют подобную сфалериту кристаллическую структуру. Для кубической модификации Cu2SnS3 и Cu2SnSe3 преимущественными плоскостями отражений являются (111), (220) и (311). Элементный состав плёнок соответствует стехиометрии соединений Cu2SnS3 и Cu2SnSe3. Методом ИК-спектроскопии определены энергии активации прямозонных переходов для Cu2SnS3 – 0.96 eV, а для Cu2SnSe3 – 0.70 eV.
