Guerra for useful discussions and suggestions.We have designed and tested an automated simple setup for measuring the profile and spot size of a Gaussian laser beam, which exhibits a similar performance to ready-made optical devices, using three light sensors. We use a light dependent resistor as a novel instrument in this approach with good accuracy. We provide the setup in detail in order to be reproduced with the current technology at a standard laboratory. Two profiling techniques were implemented: the imaging technique for the CMOS 2D array (webcam) and scanning knife-edge-like technique using a single photodiode and a light dependent resistor. We apply up-to-date devices, such as a Raspberry Pi, for automation. The methods and sensors were compared to determine their accuracy using lasers of two different wavelengths and technologies. We verify that it is possible to use a webcam to determine the profile of a laser with 1% uncertainty on the beam waist, 1.5% error on the waistline position, and less than 3% error in determining the minimum spot radius. We show that it is possible to use a light dependent resistor to estimate the laser spot size with an 11% error. The photodiode measurement is the most stable since it is not affected by the change in laser intensity. © 2021 Author(s).Fondo Nacional de Desarrollo Científico y Tecnológico - FondecytengAmerican Institute of Physics Inc.AIP Advancesinfo:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by/4.0/Stepper motorsGaussian beam-1Analog-to-digital converter-1Photodiodes-1Photoresistors-1Lasers-1Optical devices-1https://purl.org/pe-repo/ocde/ford#2.02.02-1Laser spot measurement using simple devicesinfo:eu-repo/semantics/articlereponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#20.500.12390/3020oai:repositorio.concytec.gob.pe:20.500.12390/30202024-05-30 15:26:14.578https://creativecommons.org/licenses/by/4.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="8264ced2-273c-4ccf-8f02-51d059e2e8c9"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Laser spot measurement using simple devices</Title> <PublishedIn> <Publication> <Title>AIP Advances</Title> </Publication> </PublishedIn> <PublicationDate>2021</PublicationDate> <DOI>https://doi.org/10.1063/5.0046287</DOI> <SCP-Number>2-s2.0-85109392641</SCP-Number> <Authors> <Author> <DisplayName>Bonnett Del Alamo M.</DisplayName> <Person id="rp08635" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Soncco C.</DisplayName> <Person id="rp08636" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Helaconde R.</DisplayName> <Person id="rp08637" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Bazo Alba J.L.</DisplayName> <Person id="rp07364" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Gago A.M.</DisplayName> <Person id="rp00854" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>American Institute of Physics Inc.</DisplayName> <OrgUnit /> </Publisher> </Publishers> <License>https://creativecommons.org/licenses/by/4.0/</License> <Keyword>Stepper motors</Keyword> <Keyword>Gaussian beam</Keyword> <Keyword>Analog-to-digital converter</Keyword> <Keyword>Photodiodes</Keyword> <Keyword>Photoresistors</Keyword> <Keyword>Lasers</Keyword> <Keyword>Optical devices</Keyword> <Abstract>We have designed and tested an automated simple setup for measuring the profile and spot size of a Gaussian laser beam, which exhibits a similar performance to ready-made optical devices, using three light sensors.
