Sorry about the Unclear question, I have only the data about average power of laser diode but have no idea to calculate the photon number per pulse in the experiment.f95toli said:It is not entirely clear what you are asking. What information do you have? Do you have some way of measuring the energy/pulse (before the attenuators) directly?
I am not an expert in this field (I've done some work on single microwave photons, but that is a bit different) but presumably you could get a good estimate if you know the average power and duty cycle of your laser as well as the frequency of the generated light.
I hope that is the output power, not the power consumed ?Pattarasak said:I have only the data about average power of laser diode
The photon/pulse count of a laser diode can be calculated by multiplying the energy per pulse by the number of pulses per second. This value can also be expressed as the product of the pulse repetition rate and the number of photons emitted per pulse.
The energy per pulse of a laser diode can be calculated by dividing the total energy output of the laser by the number of pulses emitted per second. This value can also be determined using the laser's pulse energy and average power values.
The number of pulses per second of a laser diode can be determined by dividing the laser's pulse repetition rate by the pulse duration. This value can also be calculated by dividing the total number of photons emitted per second by the number of photons emitted per pulse.
The photon/pulse count of a laser diode can be affected by several factors, including the laser's output power, pulse duration, and pulse repetition rate. Other factors such as temperature, external stimuli, and aging can also impact the photon/pulse count.
The photon/pulse count of a laser diode can be increased by increasing the laser's output power, pulse repetition rate, or pulse energy. Other methods such as using a higher efficiency laser or optimizing the laser's operating conditions can also help increase the photon/pulse count.
