Python interface for a Big Sky YAG Laser.

Example

from big_sky_yag import BigSkyYag

resource_name = "COM4"

yag = BigSkyYag(resource_name = resource_name)

# print the status of the laser
print(yag.laser_status)

# set the flashlamp frequency
yag.flashlamp.frequency = 10.0 # Hz

# set the flashlamp voltage
yag.flashlamp.voltage = 900 # V

# set the q-switch delay
yag.qswitch.delay = 150 # ns

# start the water pump
yag.pump = True

# open the shutter, activate the flashlamp and enable the q-switch
yag.shutter = True
yag.flashlamp.activate()
yag.qswitch.start()

# stop the yag from firing
yag.qswitch.stop()
yag.flashlamp.stop()

Change Firing Mode

The flashlamp and Q-Switch can be triggered either internally, externally, or in case of the Q-switch also in burst mode.

Flashlamp

• internal trigger

  yag.flashlamp.trigger = "internal"
  

• external trigger

  yag.flashlamp.trigger = "external"
  

Q-Switch

• internal

  yag.qswitch.mode = "auto"
  

• burst

  yag.qswitch.pulses = 10 # nr. pulses in burst mode
  yag.qswitch.mode = "burst"
  

• external

  yag.qswitch.mode = "external"
  

Other commands

• save the current configuration

  yag.save()
  

• retrieve the serial number

  yag.serial_number
  

• flashlamp counter

  yag.flashlamp.counter
  

• flashlamp user counter

  yag.flashlamp.user_counter
  yag.flashlamp.user_counter_reset()
  

• q-switch counter

  yag.qswitch.counter
  

• q-switch user counter

  yag.qswitch.counter_user
  

• nr. pulses to wait before starting the q-switch

  yag.qswitch.pulses_wait
  

• single q-switch shot

  yag.qswitch.single()
