Random lasing of microporous surface of Cr2+:ZnSe crystal induced by femtosecond laser
We demonstrate a random lasing emission based on microporous surface of Cr2+:ZnSe crystal prepared by femtosecond pulsed laser ablation in high vacuum (below 5 × 10−4 Pa). The scanning electron microscope results show that there are a mass of micropores with an average size of ∼13 μm and smaller one...
