Python script to simulate a Laser Etch Monitor (aka. Laser Endpoint Detection).
* [https://github.com/lbolla/EMpy/blob/master/examples/ex_laser_etch_monitor.py Example: Laser Etch Monitor on EMpy repository]

=== Usage ===
# Make sure you have a Python installation running, that includes scientific libraries. The easiest method is to use the all-in-one installer "[https://www.anaconda.com/download/ Anaconda]". This also installs the Matlab-like IDE "Spyder".
# Download the EMpy repository by Lorenzo Bolla: https://github.com/lbolla/EMpy
# Move "ex_laser_etch_monitor.py" & "nk.py" out of the examples folder, so they're in the same directory as the "EMpy" library folder.
# Edit "ex_laser_etch_monitor.py" to reflect your structure.
## Set up your materials, layers, and then multi-layer stack
## You can use multipliers to produce repeating layers, as so:
### ''layers = [air] + '''5 * [GaAs_DBR, AlGaAs_DBR]''' + [GaAs_substrate]''
# In Spyder, run the script with "Interact with shell after execution" enabled. This allows you to keep messing with the figure and objects after execution, like in Matlab.
