翻译成英文：尽管这些激光系统可以在低温冷却下获得高功率和高光束质量但是包含冷却系统的此类激光器装置复杂体积庞大而且低温冷却让其在很多领域难以使用

Although these laser systems can achieve high power and high beam quality under low-temperature cooling, laser devices that include cooling systems are complex and bulky, and low-temperature cooling makes them difficult to use in many fields.
