Question 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 I'm finding ways). I will be making a laser diode as is in the schematic but since I need an oscilloscope to view the wave formed by the laser diode (green) I used NI MULTISIM. thanks so much.
The one I made in the attachments is laserdiode.jpg and the schematic i copied is glpdrv4.gif. My multisim is also attached.

EDIT:

Okay I had it working now, but the wattmeter is my problem doesnt read power output! I connected the multimeter on Q1 (- and + of multimeter) and it reads okay. but there's no reading on wattmeter and the oscilloscope wave is also a problem shows square wave instead of sine wave, varies when I continually press switch (space)... need help and explanation.

I dont know the rules since I'm new so kindly bear with me. I didnt know this is considered as spamming. anyways i need urgent help thanks. also I attached a multisim file. please tell me what's wrong with the circuit i copied.

Refer to this thread for info on your questions...

Newbie here. NI Multisim green laser diode help?

BTW it is considered Spamming the Forum to open
the same thread in different Forum sections...

sorry i'm just new. I just registered yesterday so i dont know the rules. i posted the original tho. the link but i get no replies. and kindly read the EDIT. im now asking different questions. I cant change the topic name anymore.

need some urgent help maybe you could help now in what i'm asking since i know what i did is considered as spamming as you informed me.

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

You can't use a random photodiode. That circuit only works if you use the integrated photodiode right behind the laser diode (that third pin that nobody uses). Otherwise you have no feedback and you either blow it up, or nothing happens at all. I think it will be quite difficult to simulate that in multisim. The feedback path goes through a light stage, and multisim is only good at electrical.

but I had some results when i replaced the zener. i simulated the whole circuit with connected oscilloscope turns out there was a triangular wave i dont know what that meant.

I guess you will need to build the actual circuit to
see if the simulation is correct in the real world...

You made a thread asking for advice. Here is my advice: the circuit you posted will not work in multisim. Garbage in - garbage out.
