Abstract
A method of transmitting light is disclosed. The method comprises: transmitting a first light pulse into a medium to form in the medium a filamented region that is capable of guiding light, and transmitting a second light into the filamented region, wherein the second light is a pulsed light or continues wave light, and wherein the second light is transmitted at least 10 nanoseconds after the first light pulse.
Claims27
A method of transmitting light, comprising:
- transmitting a first light pulse into a medium to form in said medium a filamented region characterized by a refractive index higher than a refractive index of said medium in the absence of said light pulse;
- and
- transmitting a second light pulse into said filamented region, at an angle selected to effect a two-dimensional spatial confinement of said second tight pulse in said filamented region such that said second light pulse is guided by said filamented region,
- wherein said second light pulse is transmitted at least 10 nanoseconds after said first light pulse.
A system for transmitting light, comprising:
- at least one light source configured for transmitting light pulses;
- and
- a controller configured for activating said at least one light source to transmit a first light pulse into a medium to form in said medium a filamented region characterized by a refractive index higher than a refractive index of said medium in the absence of said light pulse, and to transmit a second light pulse into said filamented region at an angle selected to effect a two-dimensional spatial confinement of said second light pulse in said filamented region such that said second light pulse is guided by said filamented region,
- wherein said second light pulse is transmitted at least 10 nanoseconds after said first light pulse.
A method of generating a refractive index pattern, comprising:
- transmitting first pump pulse into a medium along a first direction, and a second pump pulse into said medium along a second direction, each of said first and said second pump pulses being selected to effect a transient change in the refractive index of said medium;
- wherein said first and said second directions are selected to intersect each other at an intersection region, and to form in said intersection region a refractive index pattern corresponding to an interference pattern of said pump pulses;
- wherein the method comprise transmitting probe light to said refractive index pattern to effect diffraction of said probe light by said refractive index pattern.
A method of transmitting light, comprising:
- transmitting a first light pulse into a medium to form in said medium a filamented region capable of guiding light;
- and
- transmitting a continuous light into said filamented region, at an angle selected to effect a two-dimensional spatial confinement of said continuous light in said filamented region such that said continuous light is guided by said filamented region,
- wherein said continuous light is transmitted at least 10 nanoseconds after said first light pulse.
A system for transmitting light, comprising:
- at least one light source configured for transmitting light pulses;
- and
- a controller configured for activating said at least one light source to transmit a first light pulse into a medium to form in said medium a filamented region capable of guiding light, and to transmit a continuous light into said filamented region, at an angle selected to effect a two-dimensional spatial confinement of said continuous light in said filamented region such that said continuous light is guided by said filamented region,
- wherein a diameter of a focal point of said first light pulse is from about 50 μm to about 200 μm, and wherein said continuous light is transmitted at least 10 nanoseconds after said first light pulse.
