Description

technical field [0001] The invention belongs to the field of laser technology, in particular to a pulsed laser Q-switching device. Background technique [0002] Non-linear effects can be produced when the three states of matter, solid, liquid, and gas, which are common to people, interact with laser light. However, solid crystals have the disadvantages of large absorption coefficient, low damage threshold and difficulty in repairing after damage; gas has the disadvantage of small gain coefficient due to its small material density; the characteristics of liquid are between gas and crystal, but liquid has the disadvantage of being incompressible. Density, damage threshold and gain coefficient are not easy to adjust; therefore, the common three states of matter are difficult to use in the study of nonlinear effects of high-energy and intense lasers. [0003] Supercritical fluid (SuperCritical Fluid, referred to as SCF) is a single-phase fluid above the critical temperature and...
