We have developed a mid-infrared (mid-IR) tunable Cr:CdSe laser with nanosecond pulse operation. A broad tuning range from 2.25 to 3.08 µm and an output energy exceeding 4 mJ at 2.64 μm were demonstrated. The maximum energy conversion for absorbed energy reached 35% when the pump fluence was 2.1 J/cm. We showed that Cr:CdSe is an attractive laser material for obtaining high-energy pulses in the mid-IR region and that the Cr:CdSe laser has high potential for laser biomaterial processing.
我们已经研制出一种具有纳秒脉冲运转的中红外（mid-IR）可调谐Cr:CdSe激光器。展示了从2.25至3.08 µm的宽调谐范围以及在2.64 µm处超过4 mJ的输出能量。当泵浦能量密度为2.1 J/cm时，吸收能量的最大能量转换率达到35%。我们表明，Cr:CdSe是一种用于在中红外区域获得高能量脉冲的有吸引力的激光材料，并且Cr:CdSe激光器在激光生物材料加工方面具有很高的潜力。
