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(diǎn)為人眼安全波長(zhǎng)，高峰值功率，短脈沖持續(xù)時(shí)間和高衍射波束質(zhì)量，尺寸小，重量輕。
當(dāng)今許多激光測(cè)距產(chǎn)品波長(zhǎng)都在近紅外905nm到1064nm光譜范圍內(nèi)。在應(yīng)用的功率級(jí)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(quán)衡。
相反，我們的DPSS激光器光譜在1534nm。在這個(gè)波段激光測(cè)距系統(tǒng)的配置是不需考慮降低光束的功率和質(zhì)量來(lái)進(jìn)行妥協(xié)的。
產(chǎn)品特點(diǎn)：
①人眼安全： Class-1
②高峰值功率：可達(dá)120 kW
③光束質(zhì)量：M 2 < 1.15 * DL(where DL is the diffraction limit)
④脈沖寬度：4–7 ns
⑤壽命長(zhǎng)：> 5千萬(wàn)次的發(fā)射
⑥寬溫度范圍：-45℃ – 65℃
