Inorganic perovskitenanostructures have attracted considerable attention for their tunable band gaps and excellent optoelectronic properties.It is inevitable that phase segregation of halide perovskite usually occurs ...
We demonstrated a new type of MAX phase material,chromium titanium aluminum carbide(Cr_(2)TiAlC_(2)) polymer film,to generate a passively Q-switched erbium-doped fiber laser(EDFL).The film thickness was measured to be...

Visual near-infrared imaging equipment has broad applications in various fields such as venipuncture,facial injections,and safety verification due to its noncontact,compact,and portable design.Currently,most studies u...
A passively Q-switched all-fiber laser is demonstrated using a 10-cm-long bismuth-doped fiber(BDF) as a saturable absorber(SA). The dual-wavelength operation was obtained due to the nonlinear effect inside the fabrica...
