Abstract：
 In order to overcome disadvantages of high cost and complex structure existed in laser device in high power and long wavelength, the invention discloses new type structured cascading optical parametric oscillation laser device (OPOLD) in high average power. Using polarized beam splitter component couples a sect of resonant cavity to annular cavity. 90 degrees polarization rotator is placed in the annular cavity to constitute circulated resonant cavity of polarized light. Laser in cavity can realize polarization state circulated resonant of polarized light in two frequencies or near degeneracy. First stage OPOLD and second stage OPOLD are placed at suitable positions in optical path of the resonant cavity. First stage OPOLD outputs degenerate or near degenerate laser pumps second stage OPOLD to output laser in long wavelength. Features are: simple structure, low cost, and high utilization efficiency.
