Tailoring Whispering Gallery Lasing and Random Lasing in A Compound Cavity

Tailoring Whispering Gallery Lasing and Random Lasing in A Compound Cavity

A compound cavity was proposed to achieve both whispering gallery mode (WGM) lasing and random lasing. The WGM-random compound cavity consisted of a random structure with an annular boundary, which was fabricated by a method combining both inkjet printing and metal-assisted chemical etching methods....
