Is it possible to model a photodiode PIN InGasAS,in MicroCAP 12 or LTspice?

Hi,
The sensor has a diameter of 1mm.
The area is Pi x d / 4 = 0.78 mm2.
You have a power density of between 100W and 100mW per cm2
So this is 1W to 1mW per mm2
The datasheet shows the photodiode is non-linear above 8mW:
It doesn't look like you have the right sensor. I suggest that you talk to the manufacturer.

Marco:
Or use an attenuator.
Weiiseste:
I am sorry. I wanted to say. between 100W and 10uW/m^2. :)
Thank you.

"between 100W and 10uW/m^2"
LOL
If that's correct you'll have to lower that range quite a bit, these transistor circuits can only keep the pulse shape over a range of about 100:1.
I don't know what the phododiode's currents are or the pulse widths from this thread.

Yes that is what I was thinking:
10uW m-2
On the area of the sensor 0.78mm2
0.78E-6 m-2
10E-5 x 0.78E-6 = 7.8E-11
or 78 pA
