초록

초소형 마이크로 칩 형태의 새로운 레이저 매질인 Nd:LSB(Nd$^{3+}$ :Lasc$_3$(BO$_3$)$_4$/. lanthanum scandium borate)chralski pulling method에 의해 성장하여 광학 특성 조사 및 레이저 발진 실험을 하였다. 광학적, 화학적, 역학적 특성을 모두 그대로 유지한 채 높은 농도로 Nd$^{3+}$ 이온의 도핑이 가능한 Nd:LSB의 결정 특성 및 광학 특성을 기존의 다른 Nd형 레이저 매질과 비교하고, 흡수 및 형광 스펙트럼과 형광 수명 등을 조사하였으며. 결정 구조를 분석하였다. 또한 Ti:sapphi e 레이저를 펌핑 광원으로 하였을 때 레이저 발진 특성을 조사하였다.

A new laser material, Nd:LSB $(Nd${3}:LaSc_3(BO_3)_4$, lanthanum scandium borate), of microchip type was grown by the Czochralski pulling method, and tested for optical and lasing properties. Nd:LSB, able to be highly doped with $Nd^{3+}$ ions while maintaining good optical, chemical, mechanical properties, was compared to another Nd-type laser material. The absorption and fluorescence spectra, and fluorescence lifetime were measured, and the crystal structure was analyzed. The lasing characteristics were investigated by using Ti:sapphire laser as a pumping light source.
