Laser Output as a function of time From design point of view we can say that output of all lasers is not constant. Different types of applications require different types of lasers. Therefore the output from the laser can be altered by changing its magnitude over a period of time. Thus the time related modes of laser operation are
Pulsed laser: Pulse Energy (Joules) = Average Power (Watts) / Repetition Rate (Hertz) Let’s put some real values in there and assume that you are working with a laser that has a fixed 200 W output and a repetition rate that can be tuned from 20 Hz to 1 kHz. If you set the control at 20 Hz, we have 200 W / 20 Hz = 10 J per pulse.
What is a Laser Sensor? This Wenglor OPT Long Range (Transit Time) Laser Sensor is available from AutomationDirect and uses time-of-flight technology to accurately measure distance. Time-of-flight laser distance sensors are available in a measurement range from a 1 cm to over 100 m and are similar in size, output options and laser sensing capabilities to CMOS sensors.
