600kHZ的时候是10W,不知道低频10k-50kHz的时候怎么样。应该是腔外倍频绿光激光器。加工材料也不一定就是脉宽越窄越好。个人还是支持端泵的532nm激光器。

真有1ns吗?还有啥消息介绍下?
找到了。

Green Pulsed Ytterbium Fiber Laser
IPG Photonics New Pulsed Ytterbium 10W green fiber laser provides the high single-mode beam quality, ease of use and high reliability that IPG’s fiber lasers are known to deliver at lower prices than other competitive green lasers.
IPG's green pulsed fiber lasers provide a high peak power with scalable average output power up to 10W, pulse duration of 1 ns only and frequency of 50 to 600 kHz. The novel fiber laser is much more efficient and compact than conventional lasers now on the market, and is ideal for applications in the solar/photovoltaic arena, resistor trimming and marking of transparent materials. Featuring M2 of less than 1.2, the new green pulsed laser includes a collimator, and narrow line width at 532 nm. Higher output powers are planned.
600kHz时14uJ,约1ns,平均功率10W。峰值功率大概推算约17kW。 |
