UV–Vis Spectrometers

UV–Vis Spectrometers

The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell.

Utilized a UV laser diode emitting at 378.5 nm for continuous wave (CW) laser operation.

Analyzed the dependence of laser efficiency and threshold on pump wavelength and ESA.

Main Results:

Identified that strong ESA at certain UV pump wavelengths induces thermal effects, hindering laser performance.
Demonstrated CW laser operation of a Tb³⁺:LLF laser pumped by a 378.5 nm UV laser diode.
Achieved slope efficiencies of 36% at 542/544 nm and 17% at 587 nm, with a low threshold of 4 mW.

Conclusions:

UV pump wavelength selection is critical for optimizing Tb³⁺:LLF visible laser performance by avoiding strong ESA.
UV laser diode pumping is a viable and efficient method for Tb³⁺-based lasers.
The developed Tb³⁺:LLF laser shows high efficiency and low threshold, suitable for various applications.
