LASER/LED LIGHT OUTPUT
This circuit uses a large 1cm X 1cm silicon PIN photo diode and a transimpedance amplifier to measure the light power output of infrared and
visible LEDs and laser diodes. It can be modified to produce almost any milliwatts to volts scale factor. It can be connected to either a
multi-meter or an oscilloscope.

Laser Communication System:
This is a simple Laser communication system. It can transmit and receive signal from any audio device.Communication distance is few meters.
All components are not critical. Transistor 2N2222 may be on the coolrib. Laser diode is from laser pointer (added 6/03)
