tor_lens - filters the beam through the toroidal quadratic phase corrector.

Calling Sequence

[field_out]=tor_lens(field_in, R, f[, x_shift[, y_shift]])

Parameters

• field_in :input field. it must be diffractive wavefront.
• R : the radius of the len in meters.
• f : the focal length of the len in meters.
• x_shift : the shifts of the X direction in meters(zero is defaulted).
• y_shift : the shifts of the Y direction in meters(zero is defaulted).
• field_out : the output field or diffractive wavefront.

Description

filters the beam through the toroidal quadratic phase corrector.

Examples

	f1=begin(0.04,1e-6);
	f2=circ_ap(f1,0.02);
	f3=tor_lens(f2,0.02,8);
	field_plot(f3);
