General common faults and treatment measures: 1. The reason why the laser laser output power is weak is that the new equipment is not used for a long time: 1 Whether the measured laser output power at the factory reaches the technical index; 2 Whether the accuracy of the cavity adjustment meets the requirements; 3 Whether the full-reflection film has light leakage; 4 Whether the sound and light switch insertion loss is within the specified range. 2. After using for a period of time, the laser laser output power drops: 1 Whether the laser cavity changes: fine-tuning the cavity lens to make the output spot the best; 2 All the reverse and the output diaphragm are stained; 3 Acousto-optic crystal shift or low output energy of acousto-optic power supply: adjust the position of the sound and light crystal; 4 Whether the temperature difference between the cooling water tank water temperature setting and the ambient temperature exceeds 5 °C; 5 Whether the service life of the xenon lamp has expired; 6 The laser entering the galvanometer is off center: adjusting the laser; 7 If the current is adjusted to about 20A, the sensitivity is not enough: the xenon lamp is aging and the new lamp is replaced. Abnormality cause elimination method 1. The power indicator is off. 1) AC 220V is not connected. 2) The indicator light is broken. Connect the power cord to replace it. 2. The protection indicator is on and there is no RF output. 1) Internal overheating, protection unit action. 2) The outer protection contact is disconnected. 3) The Q component does not match the driver, or the connection between the two is unreliable, causing excessive reflection and causing the internal protection unit to operate. Improve heat dissipation conditions. Check the outer protective contacts. Measure the standing wave ratio. Consult with the company. 3. The running indicator is on and there is no RF output. 1) The light control signal is always valid. 2) The RUN/T-on/T-off selector switch is not in the correct position. Check the light control signal pulse. Turn the switch to the correct position. 4. Processing graphics are confusing. The light output effective level setting is incorrect. Reset the light effective level. 5. The laser power can be turned off to be small. 1) There is a problem with the Q switching element. 2) The output RF power is too small. Check the Q switch. Adjust the output RF power. 6. The peak power of the laser pulse is too small. 1) The average laser power is too small. 2) There is a problem with the Q switching element. Adjust the light path. Check the Q switching element.
