We demonstrate that diode laser self-mixing interferometry can be exploited to instantaneously measure the ablation front displacement and the laser ablation rate during ultrafast microdrilling of metals. The proof of concept was obtained using a 50-μm-thick stainless steel plate as the target, a 120?ps/110?kHz microchip fiber laser as the machining source, and an 823?nm diode laser with an integrated photodiode as the probe. The time dependence of the hole penetration depth was measured with a 0.41?μm resolution. 相似文献
