Manual Shutter (Beam Stop)
The laser head is equipped with a manual shutter, which functions as the beam stop, capable of preventing human
access to laser radiation. The aperture location and the open and close positions of the shutter are indicated on the
top surface of the laser head.
For fiber pigtailed option, the fiber end cap is considered the ‘manual shutter’
Key Control
The CDRH compliant model comes with a key-switch on the Controller which must be connected for the laser to
operate. When the key is in the OFF position, the diode is prevented from emitting. The key must be actively turned
to the ON position each time the laser is powered on. When the key is removed from the system laser radiation is not
accessible.
Laser Radiation Emission Warning
The Controller incorporates information LEDs which display whether power is connected, the laser is on, or a fault has
occur
red. The “ON” LED is illuminated whenever the device is emitting or could emit light. See section
3.4 for details
on the controller. The emission warning indicators are also visible in the Cobolt Monitor
™
software, see section 8 for
details on the control software
Equipment Safety
Always install the laser system to a properly grounded power outlet. The laser head and controller must be mounted
on a common ground plane, such as an optical table. Cobolt lasers contain a laser diode which is sensitive to
electrostatic discharge (ESD).
Laser light reflected directly back into the laser head can be damaging to the laser. Choose Cobolt 04-51 lasers where
higher immunity to back reflections is required.
It is important to always make sure the fiber end-face is clean before turning the laser on and before connecting the
fiber connector in physical contact with another connector. Failure to do so may lead to irreparable damage of the
fiber end-face. Do not clean the fiber when the laser is on. We recommend using appropriate equipment for fiber
cleaning and inspection.
