transition in Nd:YAG. Both laser beams are oscillated in two sub-cavity
and a KTP with type II Critical Phase Match (CPM) is used at the overlap of the two fundamental laser beams to realize the 589 nm SFM laser. An output power of 340 mW continuous-wave TEM

factor of less than 1.2. The power instability is less than ±3% within 4 h. Doubly resonant is an effective solution to realize 589 nm all solid state yellow laser pumped by LDA.
