理论与实验研究了激光二极管侧泵平-平非对称腔.理论分析表明,当谐振腔运行于热稳区边缘时,激光棒内基模半径随泵浦功率迅速增加,使光束质量快速提高并保持较高的输出功率.由于该谐振腔运行于热稳区边缘的特性与近半球面腔相近,所以将此设计称为热近半球面腔.与运行于稳区边缘的平-平对称腔相比,热近半球面腔设计有助于缩短谐振腔腔长.在对热近半球面腔实验研究中,光束质量随泵浦功率迅速增加以及输出功率饱和现象被观察,实验研究与理论分析吻合较好.
Theoretical and experimental study of the side-pump laser diode flat-asymmetric cavity.The theoretical analysis shows that when the resonant cavity runs in the edge of the thermal stability zone, the base radius of the laser rod increases rapidly with the pump power, and the beam quality is rapidly increased To maintain a high output power.As the resonant cavity at the edge of the thermal stability of the characteristics and near the hemisphere cavity is close, so this design is called hot near hemispherical cavity .With the stability of the edge of the flat - flat symmetrical cavity In contrast, the thermal near-hemispherical cavity design helps to shorten the cavity length.In the experimental study of the thermal near-hemispherical cavity, the beam quality increases rapidly with the pump power and the output power saturation is observed, and experimental and theoretical analysis Good agreement.
