High-power all-solid-state single-frequency continuous-wave (CW) lasers have been applied in basic research such as atomic physics, precision measurement, radar and laser guidance, as well as defense and military fields owing to their intrinsic advantages of high beam quality, low noise, narrow linewidth, and high coherence. With the rapid developments of sciences and technologies, the traditional single-frequency lasers cannot meet the development needs of emerging science and technology such as quantum technology, quantum measurement and quantum optics. After long-term efforts and technical research, a novel theory and technology was proposed and developed for improving the whole performance of high-power all-solid-state single-frequency CW lasers, which was implemented by actively introducing a nonlinear optical loss and controlling the stimulated emission rate (SER) in the laser resonator. As a result, the output power, power and frequency stabilities, tuning range and intensity noise of the single-frequency lasers were effectively enhanced.
高功率全固态单频连续波(CW)激光器因其具有光束质量高、噪声低、线宽窄和相干性高的固有优势,已应用于原子物理、精密测量、雷达和激光制导等基础研究以及国防和军事领域。随着科学技术的飞速发展,传统的单频激光器已无法满足量子技术、量子测量和量子光学等新兴科学技术的发展需求。经过长期努力和技术研究,提出并开发了一种新颖的理论和技术,用于提高高功率全固态单频连续波激光器的整体性能,该技术通过在激光谐振器中主动引入非线性光学损耗并控制受激辐射率(SER)来实现。结果,单频激光器的输出功率、功率和频率稳定性、调谐范围和强度噪声得到了有效提高。
