OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016
Laser Head
The Laser Head contains a pump diode, laser cavity, beam shaping optics and thermoelectric coolers (TEC) routing
optics and an integrated AOM. The laser head contains an optical feed-back loop which measures the output power.
The Laser Head gets electrical power and control signals from the Controller via a 26-pin HD Sub-D cable. The AOM
does not require electrical power. There is an SMA connector on the laser head for the input modulation signals.
Laser Controller
The Controller supplies driving current and control signals to the Laser Head. All Laser Heads are delivered with a
controller. The operation set points are specific to each Laser Head and have been fixed during manufacturing. The
operation set points are stored in the laser head so the controller can be interchanged or replaced.
The status of the laser operation is given via LED indicators:
POW
(green light)
Power is supplied.
ON
(orange light)
Laser light is on in constant current mode.
LOCK
(orange light)
Laser light is on and the output power has been locked to set point. The laser is
operating according to specifications.
ERR
(red light)
An error has occurred. No laser light.
When power is supplied to the Controller, regardless of on/off state, the temperature control elements are operating
to reach set point values. The Controller includes a remote interlock connector, pin 1-2 according to Section 4.3. The
operation of the laser can be controlled and monitored via the data port that supports either USB or RS-232
commands. See Section 7 for further details. RS-232 controllers may also be delivered with a RS-232 to USB adaptor.
