    HELP!! Is an Optical Power Meter different from LPM?

    there's no LPM in our country available i decided not to buy online abroad as some people say it's a bit "dangerous" and money risking. but there is so called optical power meter... can i use it as a sub for Laser power meter? or it's very different? thanks!:beer:

    How to determine the Intensity or power of laser beam...?

    How to determine the Intensity or power of laser beam knowing only the beam divergence and beam diameter? I have a 200mW laser pointer since it's China made I have to recalculate. The I have a beam divergence equation =2arctan(d'-d/2L) and beam diameter experimentally (measured manually) So...

    Advanced math/physics oriented: Alternatives for measuring laser beam diameter?

    Hi! I hope this thread is considered as laser measurements. Okay, so I'm trying to get intensity of the EMW (laser) with formula I=P/A power/ area. know knowing this, i have 100mW cylindrical/ circular beam of laser so A=pi*r^2. now how in the H should i know what my radius is? I've searched...

    Help! Changing laser button into switch connected to a power source

    I would be using a green laser (100mW) for an experiment as for now. I'm planning to modify the laser's button turn it into switch type and I would not be using button cells i'll replace it into connected power source (battery compartment) to give me consistent voltage. No clue what how to do...

    How to connect laser diode made in an oscilloscope in NI MULTISIM?

    I made a copied green laser diode from Sam's. I'm not sure if I did things correctly I just copied the same exact schematic. Where should I connect the terminals of oscilloscope to the laser diode? and where do I connect the multimeter. Im working on an experiment (that I dont know how to do so...

    Newbie: How do I modify a laser pointer's button into knife switch(connected to...) ?

    I'm having a trouble of how modify a laser pointer button. i want to turn it into a knife switch for my experiment. I will be doing a preliminary dissection on a simple 1mW laser pointer because I plan to do that green laser 100mW (which doesn't come cheap in my country). Can you guys show me...

    Newbie here. NI Multisim green laser diode help?

    I just registered minutes ago since i really like lasers (despite of few knowledge) and so i want to learn laser stuffs more; and i hope im not in a wrong section. So anyways, i have this project i'm working on about green laser diode. I copied a schematic here in Sam's laser. I found this...
