After demonstrating the ruby laser, what other type of laser did Maiman build later in 1960?

Answer

helium-neon gas laser

Theodore Maiman's contributions did not cease with his seminal solid-state ruby laser achievement in May 1960. Demonstrating versatility and a commitment to exploring different gain mediums, Maiman continued his work and, later that same year, successfully built the first working helium-neon gas laser. This second achievement highlighted the viability of gaseous active media for lasing action, contrasting with his initial success based on a crystal rod. This sequence of building both a solid-state and a gas laser so closely together underscores his significant and broad contributions to advancing laser technology immediately following the initial breakthrough.
