Abstract

A diode-pumped continuous-wave (CW) orthogonally polarized dual-wavelength (OPDW) Sm: YAlO (Sm: YAP) orange laser with the balanced output power (i.e. equal power for both wavelengths) on G→ H transition was studied for the first time. We theoretically analyzed the condition of gain-to-loss balance via two intracavity etalons to achieve the OPDW operation, and experimentally demonstrated the OPDW orange laser in a Sm: YAP crystal. At an absorbed pump power of 9.0 W, the total balanced output power at 604 nm in b-polarization and 610 nm in c-polarization were 0.85 W. The corresponding total slope efficiency and optical-to-optical conversion efficiency with respect to the absorbed pump power were 11.4% and 9.4%, respectively. The CW OPDW Sm: YAP orange laser with the balanced output power was desirable for many fields, especially for the development of UV sources.

摘要

首次研究了一种二极管泵浦连续波(CW)正交偏振双波长(OPDW)钐:钇铝石榴石(Sm:YAP)橙色激光器,其在G→H跃迁上具有平衡输出功率(即两个波长的功率相等)。我们通过两个腔内标准具从理论上分析了增益与损耗平衡的条件,以实现OPDW运转,并在Sm:YAP晶体中通过实验证明了OPDW橙色激光器。在9.0 W的吸收泵浦功率下,b偏振604 nm和c偏振610 nm处的总平衡输出功率为0.85 W。相对于吸收泵浦功率的相应总斜率效率和光光转换效率分别为11.4%和9.4%。具有平衡输出功率的连续波OPDW Sm:YAP橙色激光器在许多领域都很有用,特别是对于紫外光源的开发。
