YT2095 Posted September 18, 2003 Share Posted September 18, 2003 Is there anyone here that knows a little about Laser behavior? I have 5 lasers here, 4x 3mw and 1x 10Mw. the 10mw laser will raise thermometer temp by roughly 5 degrees C, the 3mw lasers barely over 1 deg C. so I focused all 4 lasers onto the same thermometer, expecting about a 4 deg C rise in temp, and I may as well have just used one? there was no significant difference???? why is that?

blike Posted September 18, 2003 Share Posted September 18, 2003 I believe sayo is a laser expert i personally have no idea :/ Link to comment Share on other sites More sharing options...

YT2095 Posted September 19, 2003 Author Share Posted September 19, 2003 So do any of you KNOW why that happened (or rather didn`t)? it sure beats hell outa me as to why! Link to comment Share on other sites More sharing options...
Kedas Posted September 19, 2003 Share Posted September 19, 2003 Well I think there should be a difference but if the temp rise of one is 1°C then you shouldn't expect that 4 will get you 4°C. Because it stops rising because the energy supplied is equal to the energy that is flowing away and the higher the temp the easier energy will flow away. also how much energy is reflected and how much absorbed will also depend on the frequency and material.

YT2095 Posted September 19, 2003 Author Share Posted September 19, 2003 it was a "black body" type themocouple to a digital readout. the 10mw worked great, a single 3 mw gives the same rise as all 4 do, just a little higher? that`s what I can`t understand? (also if this helps at all?. they`re all DC semiconductor lasers) Link to comment Share on other sites More sharing options...
