固体脉冲激光器
高峰值功率固体脉冲激光器
高峰值功率固体脉冲激光器，特点为人眼安全波长，高峰值功率，短脉冲持续时间和高衍射波束质量，尺寸小，重量轻。
当今许多激光测距产品波长都在近红外905nm到1064nm光谱范围内。在应用的功率级别上，这些光谱范围并非人眼安全，因此需要在性能和安全之间做出权衡。
相反，我们的DPSS激光器光谱在1534nm。在这个波段激光测距系统的配置是不需考虑降低光束的功率和质量来进行妥协的。
产品特点：
①人眼安全： Class-1
②高峰值功率：可达120 kW
③光束质量：M 2 < 1.15 * DL(where DL is the diffraction limit)
④脉冲宽度：4–7 ns
⑤寿命长：> 5千万次的发射
⑥宽温度范围：-45℃ – 65℃
