Some common Questions and Answers during Laser use
Question 1: The laser may fail to start properly after being laid aside for a period of time. Why does this problem arise, how to solve it when it happens?
Answer: If the laser tube was laid aside for a long time, when use it again,the laser module may not be able to start preionization properly.Under this situation,the electronic circuit of the laser module may test a high degree back reflection voltage, which will cause SWR fault (Laser OK Fault) so the laser can’t start work normally. When you start to use the laser tube after putting aside for a long time , it is advised to set the duty cycle of Modulation Signal less than 10% frequency less than 25KHz,this operation can avoid trigger SWR Fault. When a SWR fault already ocurred,you can add the Modulation Signal to the laser tube, the electronic circuit will send a Secondary ionization pulse which can help the laser tube heating up.
Question 2:When the laser module start to work ,it needs a certain of time for preionization reason. If we send modulation signal to the laser,could it speed up the preionization ?
Answer : No, it couldn’t . The preionization function was accomplished by the preionization electronic circuit .Once the power was connected to the laser, the preionization start to work. Adding more modulation signal to the laser can’t make the laser tube finish preionization status earlier.
Question 3: Do the fans and heat sink of the air cooling lasers need to be cleaned up regularly ?
Answer: Yes, they do . Because the dust in the air may adhere to the fans and heat sink after the fans run for a period of time, which will greatly decrease the ventilation effect of the heat sink,more serious and irreparable damage may occur if the heat can’t be ventilated properly.
Question 4: What will happen when the laser module is in overheating protection? How to handle it when it happens?
Answer: If the laser module triggers heat protection,it will stop working.When it happens,the user should do these work : 1. turn off the laser power. 2. For water cooling type laser tubes, Inspect if the water cooling machine is normally working or not. 3.For the air cooling type laser tubes, inspect if the fans are normally working or not. 4. Inspect if the fans and heat sink of the air cooling laser should make a cleaning. 5. Check if there is enough ventilation space around the air cooling laser. 6. When the above problems happen, you should wait and don’t turn on the laser tube until the laser tube temperature drops to normal level.
