Efficient and compact laser-diode end-pumped Nd:GGG simultaneous multiwavelength continuous-wave lasers at ∼1059, ∼1060 and ∼1062 nm were first demonstrated in a free-running 30 mm plano-concave laser cavity. The maximum output power was up to 3.92 W with a slope efficiency of about 53.6% with respect to the absorbed pump power. By inserting a 0.1 mm optical glass plate acting as a Fabry-Pérot etalon, a single-wavelength laser at ∼1067 nm with a maximum output power of 1.95 W and a slope efficiency of 28.5% can be obtained. Multiwavelength lasers, including those at ∼1054 or ∼1067 nm, were also achievable by suitably tilting the glass etalon. These simultaneous multiwavelength lasers provide a potential source for terahertz wave generation.
在一个30毫米平凹自由运转激光腔中首次演示了高效紧凑的激光二极管端面泵浦Nd:GGG同时多波长连续波激光器,波长约为1059纳米、1060纳米和1062纳米。相对于吸收的泵浦功率,最大输出功率高达3.92瓦,斜率效率约为53.6%。通过插入一块0.1毫米的光学玻璃板作为法布里-珀罗标准具,可获得波长约为1067纳米的单波长激光器,其最大输出功率为1.95瓦,斜率效率为28.5%。通过适当地倾斜玻璃标准具,还可实现包括波长约为1054纳米或1067纳米的多波长激光器。这些同时多波长激光器为太赫兹波产生提供了一个潜在的光源。
