Welcome to PyCoherentVerdi’s documentation!¶

Package for reading parameters of the Verdi laser

Note that the module uses property attributes. Look at the python documentation to understand how property attributes are working if you don’t alread know.

Example

verdi = VerdiDriver(port='COM7')
print verdi.power # print the measured power
print verdi.set_power # print the set power
verdi.set_power = 15.6 # set the power to 15.6 watts

verdi.list_cmd(['power', 'baseplate_temperature']) # Returns a dictionary with the values of the parameters in the list
verdi.read_all_parameters() # Returns a dictionary with the values of all the parameters

Verdi API¶

Main commands¶

class PyCoherentVerdi.VerdiDriver(port='COM7', baudrate=19200, parity='N', stopbits=1)¶

Main class for driving the Verdi laser

read_all_parameters()¶: Returns a dictionary with all the parameters

read_list_cmd(liste_cmd)¶: Returns a dictionary with all the parameters of liste_cmd

set_power¶: Returns or set the light regulation set power in watts

shutter¶: Returns or set the status of the external shutter {0:”CLOSED”, 1:”OPEN”}

laser¶: Returns or set the laser status (OFF, ON)

enable()¶: Resets faults and turns laser on (key must be in the “ENABLE” position). Clears fault screen on power supply and fault history so lasing will resume if no active fault

stand_by()¶: Put the laser in STANDBY mode (note: If the key is in the “ENABLE” position, then this command will override
