Titanium doped sapphire crystal excited by diode pumped solid state laser
The laser crystal emission property is the crucial factor to produce laser. An appropriate pumping source is needed to pump atom in the crystal to an excited state which depend to the absorption band of the crystal. The emission only occurs when the threshold value is exceeded. The aim of this resea...

| description | The laser crystal emission property is the crucial factor to produce laser. An appropriate pumping source is needed to pump atom in the crystal to an excited state which depend to the absorption band of the crystal. The emission only occurs when the threshold value is exceeded. The aim of this research is to study the absorption and emission spectrum of the laser crystal during pumping process. Ti:sapphire crystal was employed as an active medium. High power diode pumped solid state (DPSS) laser was used as a pumping source. A spectrum analyzer was utilized to detect the absorption and emission spectrum of the crystal. The absorption spectrum comprised of 532.01 nm, 807.23 nm and 1064.07 nm. The major of emission spectrum is 806.80 nm with intensity achieved up to 97.46 %. The optimum emission was occurs at corresponding pumping current of 22 A. |
