Abstract We originally present the optical bistability in a dual-wavelength Yb:YAG laser for all-optical switching. The theoretical investigation of the lasing wavelengths was proposed and a plano-concave laser cavity was designed to achieve the laser oscillations. The continuous-wave, dual-wavelengths at 1030 and 1050 nm were operated in a co-linear laser beam. Optical bistability in the Yb:YAG laser was observed and attributed to the reabsorption process. The results suggested that excellent switching characteristics can be utilized to generate all-optical logic gates and simple inverter switches. The performances of the Yb:YAG provides a pathway to engineering materials for future applications based on optical bistability.

用于全光开关的二极管端泵浦双波长 Yb:YAG 激光器的光双稳性

摘要 我们最初提出了用于全光开关的双波长 Yb:YAG 激光器的光学双稳态。提出了激光波长的理论研究，并设计了平凹激光腔来实现激光振荡。1030 和 1050 nm 的连续波双波长在共线激光束中操作。观察到 Yb:YAG 激光器中的光学双稳性并归因于重吸收过程。结果表明，优异的开关特性可用于生成全光逻辑门和简单的逆变器开关。Yb:YAG 的性能为基于光学双稳态的未来应用工程材料提供了途径。
