User’s guide Ytterbium Pulsed Fiber Laser RFL-P20MB Ver.: 2.0
6)
The device has three cooling fans at the rear panel to dissipate heat. In order to guarantee
enough airflow to help giving heat off, there must be a space of at least 10 cm’s width for
airflow in front and rear side of the device. As the cooling fans are working at blow condition,
if laser is mounted in a cabinet with fans, the direction should be same as laser’s fans.
7)
Do not look into the output head of the device directly. Please do wear appropriate laser
safety eyewear during the time when operating the device.
8)
Make sure the pulse repetition rate higher than 10 kHz.
9)
For the longest time without pulse is only 100 us. If there is no pulse output, please stop
marking at once, to avoid further damage of the device.
10)
Power source sudden interruption will do great harm to the laser device. Please make sure
the power supply works continuously.
