“…The finite-element analysis method was adopted in the whole analysis. 16,17 To achieve optimization of power scaling further, the OEF as a function of the waist position and size of pump beams should be deeply investigated by including the thermal effect into the spatial rate equation analysis. So far, most of the research for mode matching degree is mainly focused on the Nd 3+ -doped crystal.…”

The power scaling of an all-solid-state visible laser is limited by the mode-to-pump ratio related to the thermal effect based on the spatial rate equation. The mode-to-pump ratio is also known as the overlap efficiency factor (OEF). We investigated the thermal effect as a function of pump power, the waist radius of pump beams, and the waist position of pump beams and have simulated the three-dimensional distribution of the OEF as a variable of the waist position and size of pump beams. Also, it is seen that the calculated optimal OEF under a plane-concave cavity is a decreasing function of input pump power, and it is less than unity in the case of high pump power. The practical example of a Pr:YLF laser pumped by 9-W fiber-coupled laser diodes confirms our theoretical analysis. The output power instability was < AE1:625% (RMS) within 1 h. In addition, by changing the cavity length to 38 mm, the output power of 607 nm is up to 103 mW with an OEF of 0.741.
