q switched nd yag laser tells you that many people know that a laser is generally composed of three parts: working material, resonator cavity and pump source. Take a solid-state laser as an example, the working substance is usually a crystal rod (or glass rod), the pump source is composed of a condenser, a flash lamp (xenon or krypton flash mirror, q switched nd yag laser tells you one of the reflections The reflectivity of the mirror is 100%, while the reflectivity of the other mirror is generally about 50%. Since this mirror has a certain transmittance to light, the laser is output from this.
q switched nd yag laser refers to a pulsed laser that adopts certain switching laser technology to obtain higher output power.
How q switched nd yag laser works:
The working principle of q switched nd yag laser is that after the particle number inversion state of the working substance is formed, it does not make it generate laser oscillation (the switch is in the off state), and when the particle number is accumulated to a high enough level, the switch is suddenly turned on instantaneously, Therefore, a very strong laser oscillation and high-power pulsed laser output can be formed in a short time (for example, 10-10 seconds).
