Abstract

We have demonstrated an efficient, high-power continuous-wave Nd:YAG laser utilizing a stacked and rotary-disk configuration for the gain medium. The disks were air-cooled at room temperature. By employing a diode laser pump power of 347 W in a fiber-coupled end-pumped setup, we achieved an output power of 205 W in the fundamental transverse mode from the simplest resonator cavity. The beam quality factors (M²) in the orthogonal directions were measured at 1.143 and 1.169, respectively. The optical slope efficiencies were approximately 68%. Additionally, the root mean square (RMS) of the laser's instability, measured continuously over a period of 6 hours, was found to be 0.276%.

205w tem00模式堆叠Nd:YAG旋转盘激光器与空气冷却。

我们已经展示了一种高效，高功率的连续波Nd:YAG激光器，利用堆叠和旋转磁盘配置作为增益介质。磁盘在室温下被空气冷却。通过在光纤耦合端泵浦装置中使用功率为347 W的二极管激光泵浦，我们在最简单的谐振腔中实现了基模横向输出功率为205 W。正交方向上的光束质量因子M2分别为1.143和1.169。光学斜率效率约为68%。此外，在6小时的连续测量中，激光不稳定性的均方根（RMS）为0.276%。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
