b_split - splits one beam into two beams.

Calling Sequence

[field_out_1,field_out_2]=b_split(field_in[,split])

Parameters

• field_in :input field. it must be diffractive wavefront.
• split : the splitting coefficient, split=0.5 if defaulted.
• field_out_1 : the output field whose intensity is sqrt(split) of the field_in
• field_out_2 : the output field whose intensity is sqrt(1-split) of the field_in

Description

b_split and b_mix are two commands useful to model interferometers. With b_split we split the field structure (amplitude division) to two field. b_split provides the possibility of amplitude division, preserving the sum of intensities of the two splitted beams. The two obtained files could be processed separately and then mixed again with b_mix .

Examples

	f1=begin(0.005,0.55e-6,512);
	f2=circ_ap(f1,0.00012,-0.0005);
	f3=circ_ap(f1,0.00012,0.0005);
	f4=b_mix(f2,f3);
	f5=forvard(f4,0.75);
	file_ps(f5,"young");
