Abstract: We report continuous-wave orange laser operation at 607.5nm of a 8mm long 0.2at% Pr:LiYF4 single crystal with an improved laser slope efficiency. Using a single InGaN laser diode emitting at ∼444nm as a pump source, an output power of ∼200mW was achieved with a threshold absorbed pump power of ∼150mW and a laser slope efficiency of nearly 42%. M 2 factors of 1.40 and 1.28 were measured in the x and y directions, respectively, attesting to the good quality of the output laser beam. [Copyright &y& Elsevier]
