１引言自１９６４年推出ＣＯ２激光器以来，使用的连续波光功率已从几毫瓦提高到１００ｋＷ以上。虽然从原则上说，可以获得两倍以上功率的这种工业激光器，但实际的工业应用领域大约只使用２０ｋＷ的功率。若考虑激光器的输出功率和其应用领域的分布，人们得出，大多用于... 1 Introduction Since the introduction of CO2 lasers in 1964, the CW optical power used has been increased from a few milliwatts to over 100 kW. Although in principle this industrial laser can be obtained at more than twice the power, only about 20 kW of power is actually used in industrial applications. If one considers the laser’s output power and the distribution of its field of application, one finds that most are used for ...
