Double-disk gain crystal double-bonded YAG once-through cooling thin disk laser

The invention relates to the technical field of laser and discloses a double-disk gain crystal double-bonded YAG once-through cooling thin disk laser. A double-thin-disk crystal structure having a left gain crystal and a right gain crystal is used. The left gain crystal and the right gain crystal constitute a double-bonded structure. The light of a left pumping system and a right pumping system are focused on the right bonding layer of the left gain crystal and the left bonding layer of the right gain crystal respectively by a deflecting mirror. A once-through cooling system cools the right bonding layer of the left gain crystal and the left bonding layer of the right gain crystal. A resonant cavity consists of an aspheric parabolic mirror and a spherical double concave mirror. The aspheric parabolic mirror is coaxial with the left gain crystal and the right gain crystal. The double-bonded and double-thin-disk structure compensates for the optical distortion caused by a thermal effectand improves the beam qua
