30 Oct 2014 Fiber Lasers and Amplifiers Design Toolbox Design toolbox allows parameter selection by solving lasers/amplifiers for various L,R,P,lambda etc Author: Luke Rumbaugh Luke Rumbaugh

Hi Atul, I think the problem is the "~" character, which has been introduced in recent Matlab versions as a way to ignore function outputs. It is not supported by older versions -- you can simply replace the ~ with "dontCare" or something similar.

Occurrences in the toolbox include AmplifierPerformance.m line 184, and LaserNumerical.m lines 123, 125, and 132.

Thanks for the heads up!

Hi Atul, sure, sorry you're having trouble. I haven't seen anyone get that error before ... If you can, please email me and tell me what system you were simulating exactly?
Click on my name and then "Contact author". Thanks!

I was trying to use Fiber Amplifier except for the first two curves, none of the following figures are generated and he following errors comes up:

Warning: Ignoring extra legend entries.
> In legend at 239
In SmallSignalGain at 179
In FiberAnalysis>CallDesiredFunctions at 289
In FiberAnalysis at 85
??? Error: File: AmplifierPerformance.m Line: 184 Column: 3
Incomplete or misformed expression or statement.

Error in ==> FiberAnalysis>CallDesiredFunctions at 294
[data hFig] = AmplifierPerformance(set);

Error in ==> FiberAnalysis at 85
[data{ii} hFig(ii)] = CallDesiredFunctions(iiSelections(ii),s);

ans =

{1x2 cell}

Can you provide some assistance to overcome this issue.

thanks

Derrek, thanks for pointing that out, the GUI doesn't really have good support for cladding-pumping yet, I'll add that soon.

Meanwhile you can look at "LaserPerformance.m" line 116 and "AmplifierPerformance.m" line 151 and following to manually adjust your overlap parameters GammaP (for the pump) and GammaS (for the signal).

Thanks

I have just started using this solver, and I am finding it incredibly useful(update: July 22 2013).

The following comment is with respect to the ytterbium laser option of the program.

It is important in some applications to be able to vary the the cladding-pump/core area ratio. Right now the program appears to pin the E-field/core area ratio to the pump/core area ratio.

It would be nice to include either an input for the pump cladding diameter, or for the overlap ratio so that this can be varied.

Looks like the original package didn't have the GetYbSpectrum and GetErSpectrum functions that provide spectroscopy data for ytterbium and erbium fibers.

I.e. the original didn't work -- SORRY!!

An update has been submitted.

At this point, anyone intending to use the toolbox, please redownload the current package.

Sorry for the semi-GUI, I'll try to have a real one up soon so you don't have to keep re-entering values.
