Laser Equipment Co., Ltd., Dongguan City Jinhui (Contact: 15218767768 Jiang Health) specializing in the production of fiber laser marking machine, laser marking machine, CO2 laser coders, laser cutting machine. International bulk purchases, important components are from famous manufacturers in Europe and America, Genius, the industry well-known brands. Product marking fast, high precision, stable performance, and to provide online flight laser marking machine for the British company Gucci Hughes ancient company (GOOCH & HOUSEGO, comprising the United States NEOS company) authorized distributors in China , authorized Chinese customers with pre-sale, service. Stock the following import British Gucci Hughes ancient company Q-switch: QS27-6.5CB, QS27-5S-B, QS27-5C-B, QS27-4C-B, QS27-4S-B, QS27-4S-S, QS27 -. 3C-S and QS27-3S-S Q-technology is the change over time according to a certain program of technology to the cavity Q value in some way. So when you start pumping chamber in a low Q value of the state, is to enhance the oscillation threshold, the oscillation can not be generated, the energy level inversion can be a lot of accumulation, when accumulated to a maximum value (saturation value), suddenly makes cavity loss decreases, Q value of the sudden increase in laser oscillation quickly built up on the inversion level in a very short period of time is consumed, transformed into light energy cavity, a single pulse at the output chamber in the form of the energy released, so you get a high peak power giant pulse laser output. Acousto-optic Q switch is the use of sound and light interact to control the loss of the optical cavity Q-switch technology. Acousto-optic Q is formed ultrasonic waves changes periodically modulated refractive index of medium through the electro-acoustic conversion of the incident light from the diffraction effect, so that diffraction losses occur, Q value decreased, laser oscillation can not be formed. In which the optical pumping excitation energy level inversion and reaches a saturation value accumulation, after the sudden withdrawal of ultrasound, diffraction effects disappear immediately, cavity Q value increases Meng, laser oscillation rapid recovery, its energy output in the form of a giant pulse . This is a widely used Q-switched mode, its main advantage is the high repetition rate, stable and reliable performance.
