Abstract

An end pumped laser having crystal or glass lasing material is provided. At least one pumping laser (LD) in optical communication with an end of the lasing material is used to pump the laser. The lasing material is composed of a laser host material doped with a laser active ion. The laser material has a first zone (Z11) having a preselected level of laser active ions. The lasing material has a second zone (Z12) located between the first zone and pumping laser. The second zone has a lower level of laser active ions than said first zone.
