Functions

list_lasers()

Return a list of laser objects for all cobolt lasers connected to the computer

Classes

class CoboltLaser (port=None, serialnumber=None, baudrate=115200)

Creates a laser object using either COM-port or serial number to connect to laser. 
Will automatically return proper subclass, if applicable. 
If you are uncertain about your laser type, initiate as CoboltLaser.

Subclasses

Cobolt06DPL Cobolt06MLD 

Methods

clear_fault()

Clear laser fault

connect()

Connects the laser on using a specified COM-port (preferred) or serial number. 
Will throw exception if it cannot connect to specified port
or find laser with given serial number

constant_current(current=None)

Enter constant current mode, current in mA. If current=None, the laser will use previously saved settings

constant_power(power=None)

Enter constant power mode, power in mW. If power=None, the laser will use previously saved settings

disconnect()

Disconnect the laser

get_current()

Get laser current in mA

get_current_setpoint()

Get laser current setpoint in mA

get_fault()

Get laser fault

get_mode()

Get operating mode

get_ophours()

Get laser operational hours

get_power()

Get laser power in mW

get_power_setpoint()

Get laser power setpoint in mW

get_state()

Get autostart state

interlock()

Returns: 0 if closed, 1 if open

is_connected()

Ask if laser is connected

is_on()

Ask if laser is turned on

send_cmd(message, timeout=1)

Sends a message to the laset and awaits response until timeout (in s).

Returns:
The response recieved from the laser is string format or
"Syntax Error: No response" on a failed attempt,
"Syntax Error: Write failed" if no connection is available

set_current(current)

Set laser current in mA

set_power(power)

Set laser power in mW

turn_off()

Turn off the laser

turn_on()

Turn on the laser with the autostart sequence.The laser will await the TEC setpoints and pass a warm-up state
