If the laser tube has been unused for more than one week, it may not be able to perform pre-ionization when it starts to use. In this case, the laser control circuit will detect a high backward reflection voltage, which will result in ‘SWR error’ & ‘Laser OK / Fault’, and cause the laser tube to fail to start normally. Therefore, in order to avoid from triggering SWR errors, it is recommended to adjust the duty cycle of the modulation…

No, it cannot, unless by modifying the program. The pre-ionization of the laser tube is done by the internal pre-ionization circuit. The pre-ionization circuitry starts to work as soon as the laser tube is switch on.  An artificial modulation signal cannot help the laser tube to complete the pre-ionization state.

Yes, it is. Due to the dust in the environment adhering to the laser fan and heat sink, it will greatly affect the cooling effect of the laser, which will lead to the heat of the laser tube cannot be effectively conducted, further causing irreparable failure of the laser.

When the laser tube is switch on, it will enter the working state. If the control PIN of the laser tube is in a suspended or high resistance state, then the electrical level on the PIN will stand in an unknown state, which may lead to the following situations: 1. A large number of noise signals on the PIN which get the laser tube damaged. 2. If there is an unknown high level on the PIN, the laser tube may…

If the laser tube gets overheat protection, it will stop working. When such a situation occurs, the user needs to do the following: (1) Switch off the power supply of the laser. (2) Check the chiller, whether the working condition is normal. (3) Check the fan, whether it works normally (4) Whether the fan and heat sink need to be cleaned. (5) Whether the peripheral heat dissipation space for the air-cooling laser tube is sufficient. (6) After eliminating the above possible failures,…

1. The laser must be stored and transported in the process to ensure that the cooling     water inside the laser is completely blown dry, and it is recommended that the laser be blown dry with dry nitrogen gas with a purity of 99.95%, otherwise the cooling water inside the laser will cause irreparable damage to the internal structure of the laser tube.  2. The laser output window must be sealed during storage and transport to protect    …

No. It cannot. PIN 7 is the control enable terminal of the laser tube. Too high switching frequency will cause laser failure. The switching frequency of signal for PIN 7 should be < 200Hz.

1. The ambient temperature needs to kept at 5 ℃~40 ℃. Air conditioners must be used when necessary.  2. Environmental cleanliness. If the laser tube under high dust level, without external dust protection equipment, It will cause the output window mirror burnt.  3. Ambient humidity.  Requires has no condensation 4. The ambient PH remains neutral.
