The book traces the laser’s roots in the maser, then surveys applications across medicine, industrial projects, space research, communications, television, radar, and precise measurement. It also covers classroom safety at low power versus high-power cutting, and highlights holography as lensless “photo-graphy” enabled by lasers. Further topics include surgery, surveying, stress measurement, and future prospects, with a postscript addressing laser “death rays.”",{"@graph":69,"@context":121},[70,84,104],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/lasers-work-like-this/567063/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":98,"encodingFormat":97,"isAccessibleForFree":99,"interactionStatistic":100},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/lasers-work-like-this/567063.png","ImageObject",300,407,{"name":92,"@type":93},"\tCallum

 \n# work like this\n\nAN ILLUSTRATED INTRODUCTION  \n# Laserswork like this\n\nby Egon Larsen  \nIllustrated by Charles Green  \nYou ask,'What is a “laser”?’  \nLASER,simply,is'Light Amplification bythe Stimulated Emission of Radiation’.  \nWith his happy knack of making difficult con-cepts lucid,Egon Larsen proceeds from definingthe laser to examining the variety of its presentuses in medicine,industrial projects and spaceresearch,and the possibilities of the future.Hestarts with the maser,the parent of the laser.Theprinciple of stimulated emission of radiation isoutlined,first with regard to microwaves,and thento the much higher frequencies of light waves.These produced for the first time a beam ofcoherent light.  \nThe author shows how,at low power,laser lightcan be safely used in the classroom.He contraststhis with its use at high power when it is capableof cutting a precisely measured hole through adiamond in a split second.He goes on to outlinethe laser's place in space communication,televisionand radar;in all kinds of precise measurement,from stress in a steel plate to movements in theearth's crust;its uses in surgery and surveying,andin computers.  \nThe exciting new subject of holography,'photo-graphy without a lens’,could probably have notcome into existence without a laser,and an explana-tion of this is also included.  \nEgon Larsen has several more books for youngscientists on the Roy list,including Radar WorksLike This,Transistors Work Like This,Transport,A History of Invention,Men Under the Sea,MenWho Changed the World,Men Who Fought forFreedom,Men Who Shaped the Future,and SirVivian Fuchs.  \nRILEY HICH SCHOOL LIBRARY  \n# LASERS WORK LIKE THIS\n\nTHE‘SCIENCE WORKS LIKE THIS’SERIES  \nTELEVISIONJ.and R.Bendick and John
