title: Five new 3-microu m laser lines in YAlO3:Er.
abstract: Five new laser lines at lambda = 2.7118, 2.8230, 2.8400, 2.8665, and 2.8756 pm were found in a YAlO3:Er (10 or 20%) crystal laser operated at 300 K. Tuning of the laser cavity in favor of the new transitions was performed with polarizing, birefringent, and selectively absorbing filters.
