Optics fluence
WebJan 1, 2024 · The optics damage inspection system are installed to measure optics damage routinely with a resolution of 100 μm. Meanwhile, the damage image is precisely measured off-line during the individual shot by microscope for the detailed morphological characteristics. ... After 50 high-fluence shots, the WFL just has several damage sites … WebThe key parameters for a saturable absorber are its wavelength range (where in the electromagnetic spectrum it absorbs), its dynamic response (how fast it recovers), and its saturation intensity and fluence (at what intensity or pulse energy it saturates). Saturable absorber materials are useful in laser cavities.
