We used a modified Paul trap and created a near-perfect spherical liquid droplet by trapping and levitating a charged, micrometer sized liquid droplet in air. The spherical micro-drop acts as a whispering gallery mode resonator. A suitable lasing material (rhodamine 6G or Rh6G dye, water soluble CdS...
