Abstract

The invention relates to the field of optical laser technology, and discloses a novel temperature-controlled furnace, which includes a base and an angle adjustment mechanism. The upper surface of the base is fixed with a shell by bolts, and the bottom inner wall of the shell is fixed with a plurality of A telescopic rod, one side of the telescopic rod is sleeved with a first spring, the top end of the telescopic rod is fixed with a mounting plate by bolts, one end of the first spring is fixedly connected to the bottom inner wall of the housing, and the other end of the first spring One end is fixedly connected with the mounting plate, a first fixed rod is mounted on one side of the housing through bearing engagement, and one end of the first fixed rod is fixed with a turret through a bolt. The invention can adjust the position of the nonlinear crystal and improve the flexibility of the device; secondly, it can irradiate the nonlinear crystal with laser, thereby changing the frequency of the laser, improving the utilization rate of the nonlinear crystal, and can irradiate the nonlinear crystal Carry out heat preservation, reduce the fluctuation of the nonlinear crystal, and improve the heat preservation effect of the device.

Description

technical field [0001] The invention relates to the field of optical laser technology, in particular to a novel temperature-controlled furnace. Background technique [0002] In the laser frequency doubling system, the frequency doubling output efficiency and its output stability are greatly affected by the external environment, and the temperature change on the nonlinear crystal is often a key factor. In the high average power laser frequency doubling system, the frequency doubling is not The linear crystal absorbs part of the laser energy, resulting in a rapid temperature change on the nonlinear crystal, and the destruction of the phase matching condition will greatly reduce the frequency conversion efficiency and stability. Therefore, it is necessary to control the temperature of the nonlinear crystal at within a certain range. [0003] After retrieval, the patent with the authorized publication number of CN109687281A discloses a temperature-controlled furnace. The temper...
