Abstract: Erbium glass lasers can directly output 1.54μm eye-safe laser and can be used in eye-safe rangefinding applications.LD bar side-pumped Er+3,Yb+3 phosphate glass laser is reported.At free-running mode maximum pulse energy of 60mJ is obtained.At 0.5Hz repetition rate,it can output 50mJ/pulse,at 1.54μm stably.Eexperiments indicate that the key of Er glass laser design is pumping symmetry and uniformity.
