“…However, when the radius of curvature and the length of cavity are fixed, the stable region of folded cavity is smaller than that of flatconcave cavity. According to our previous theoretical research on the characteristics of stable region of flat-concave cavity and three-mirror folding cavity [9][10], the length of straight arm 1 l is selected as 65mm. After inserting LBO crystal, the reciprocating matrix of three-mirror folding cavity is rewritten.…”

“…If the waist radius of the pump beam is too large, the overlap efficiency of the pump beam and the oscillating beam will also be reduced, because when the waist radius of the pump beam is too large, the pump energy can not be effectively coupled to the volume of the oscillating mode. On the basis of extensive experimental research on 1.34m fundamental frequency light [9][10], combined with the existing experimental conditions, the pump optical coupling system is redesigned. After the LD output light is shaped by the coupling system, the waist spot radius of the pump light is 120m, and the theoretical value of the waist spot radius of the oscillating light beam at the plane mirror M 1 is about 139m, so that the principle of higher overlap efficiency is accorded with when the two beams are coupled.…”

“…Neodymiumdoped yttrium vanadate (Nd:YVO 4 ) is a suitable laser crystal for a diode pumped laser owing to its high emission and high absorption cross section. [3][4][5] The Nd:YVO 4 crystal is naturally birefringent, the stimulated emission cross sections (SECS) are not equal in different crystallographic directions. The π-polarized lasing (lasing parallel to the c axis) is stronger in the Nd:YVO 4 crystal, compared with the σ -polarized lasing (lasing perpendicular to the c axis).…”
