PRADNYA GHORPADE LAB REPORT 1 MAY 28 2023 Goal The purpose of this lab is to teach participants the safety precautions required for laser experimentation as well as the quantitative measurement of light Achievements In this lab we examined the laser safety readings and learned the fundamental equations needed to resolve the issues that came up in the experiments Irradiance the energy of a single photon and how many photons per second were emitted by the VLM 635 63 LPO laser diode are some of the fundamental equations of light that are presented Both the computations and the agreement were completed Discussion 1 Based on the VLM 635 63 series data sheet what is the output power for the VLM 635 63 LPO laser diodes The output power is 0 39mW 2 Based on the VLM 635 63 series data sheet what is the area of the spot size for the 100 mm focal distance laser diode Use the 1 e2 dimensions given in the datasheet to determine the area of this spot size A 9 10 3 2 2 6 36 10 9 3 Based on the power output of the VLM 635 63 LPO laser diode and the area you found in the previous question what is the irradiance for this laser diode at the focus point Include the correct units in your answer I 39 10 3 W 6 36 10 3 m2 0 0613 W m2 4 Based on your calculation for the irradiance at the focus point of the VLM 635 63 LPO laser diode and Figure 1 from the Lab 1 handout even though this is classified as a Class I eye safe laser should it be directed into anyone s eye No the laser should never be directed towards someone s eye 5 What is the energy of a single photon from the VLM 635 63 LPO laser diode E hc 6 63 10 34 x 3 8 108 635 10 9 3 97 10 19 J 6 How many photons per second are emitted from the VLM 635 63 LPO laser diode 39 10 3 photons 3 967 10 19 sec 9 83 1014 photons secs 7 I have read through the laser safety documentation provided I understand what was presented and agree to follow the safety rules and guidelines I will not allow others who are untrained or who have not agreed to follow the safety rules and guidelines to work with the laser diode in this kit Sign below and include this in your lab report Sign PVGhorpade Results Calculated and given in discussion Raw Data No raw data for this experiment
