高峰值功率固體脈沖激光器
高峰值功率固體脈沖激光器，特點為人眼安全波長，高峰值功率，短脈沖持續時間和高衍射波束質量，尺寸小，重量輕。
當今許多激光測距產品波長都在近紅外905nm到1064nm光譜范圍內。在應用的功率級別上，這些光譜范圍并非人眼安全，因此需要在性能和安全之間做出權衡。
相反，我們的DPSS激光器光譜在1534nm。在這個波段激光測距系統的配置是不需考慮降低光束的功率和質量來進行妥協的。
產品特點：
①人眼安全： Class-1
②高峰值功率：可達120 kW
③光束質量：M 2 < 1.15 * DL(where DL is the diffraction limit)
④脈沖寬度：4–7 ns
⑤壽命長：> 5千萬次的發射
⑥寬溫度范圍：-45℃ – 65℃
