+% Gaussian beam propagation package.
+% Eugeniy Mikhailov
+% 2013
+
+# Main features
+
+Can treat lenses and empty spaces (with a given refraction index). And
+able to calculate Gaussian beam propagation via ABCD matrix formalism.
+
+## Gaussian beam travel visualization
+
+Given starting Gaussian mode parameter (q) calculates q in the given
+point(s) along optical path. There is
+
+It can propagate Gaussian beam back and force and compare the beam
+profiles after such propagation.
+
+For a quick demo run:
+
+     solution_visualization_demo.m
+
+## Mode matching
+
+Automatically search for a way to mode match a given Gaussian beam to
+desired one at given distance via set of lenses in between. Very handy
+for injection of a known beam to a single mode fiber or a cavity.
+
+It might take a while to compute but for a quick demo run:
+
+     mode_match_demo.m
+
+## Cavity design
+
+-   calculates if resonator is stable
+-   calculates and plots resonant mode profile
+
+For demo run:
+
+    cavity_design_demo.m
+
+# Brief history of the project
+
+The original code dates as old as 2004 (at least I find some files that
+old), but logged changes started only in 2006. Initially development is
+done by Eugeniy Mikhailov with first files dated by Jun 2006, but it was
+started even earlier. In 2012-2013 Matt Argao extended code to
+automatically find mode matching solution from given set of optical
+elements.
+
+## Version 4.1.1
+
+Small typos fixes. Added real life mode matching example of the fiber
+mode to the gyro cavity mode.
+
+## Version 4.1
+
+Cavity design polish up and bug fixes.
+
+## Version 4.0
+
+Cavity design module
+
+## Version 3.1
+
+Demos are added/modified
+
+## Version 3.0
+
+Addition of the automatic mode matcher
+
+## Versions 2.0
+
+Visual mode matcher check and beam propagation visualization
+
+## Version 1.0 and earlier
+
+Initial ABCD formalism and unrecorded modifications.
