OSCAR

08 Jul 2008 (Updated 03 Feb 2012)

An optical FFT code to simulate Fabry Perot cavities with arbitrary mirror profiles

File Information
Description	OSCAR is an optical FFT code used to calculate the steady state optical field circulating in Fabry Perot cavities. The code can integrate non-sperical mirrors and any arbitrary input fields. Recent applications for OSCAR have been: calculation of thermal lensing effect and calculation of diffraction loss and cavity eigen modes for mesa beams. One great advantage of OSCAR is the simplicity and flexibility of the code, everyone with only minimal knowledge of Matlab can easily modified OSCAR code to suit specific purposes.
MATLAB release	MATLAB 7.10 (2010a)
Other requirements	If beam fitting functions are needed, the Optimization Toolbox is required.

24 Feb 2010	Richard Day	This is a first class job. I have used Oscar as a foundation for my own code for simulating cavities. It is really very easy to understand the code and there is also a very well written user manual.
06 Oct 2011	Christian Vorholt	Really nice job. Documentation is easy to understand and to follow. Thanks to the author!

Updates
22 Jul 2008	A little mistake found in the manual
30 Jul 2008	Added a new example
20 Oct 2008	New version, add an example how to create sidebands and derive a Pound Drever Hall locking signal.
23 Apr 2009	Add an example about how to simulate a 3 mirrors ring cavity (also called a mode cleaner).
12 Jan 2010	Example to reduce the computational time of OSCAR, better memory allocation of matrices and correct a sign error
03 Feb 2012	The code has been fully rewritten (with Oriented Object Programming) to be faster and more user friendly. Higher order optical modes are supported.
