Supercontinuum what is it ndash simplified

Supercontinuum Output

Pulsed

laser (ps) Non linear fiber

Supercontinuum is generated when high (peak) power

light enters a nonlinear material

The enabling technology is photonic

crystal fibres (PCFs)


5

Supercontinuum - The difference

Merged set of conventional lasers One Single Supercontinuum Source

NKTs role PCF for 2 microm


11

Thermal light source Broad spectral coverage and low cost

Power spectral density in a single mode fiber lt50 dBmnm

OPOs Up to 10 W in a ultra-narrow line tunable over up to 700 nm

High cost system for lab use only

Mid-IR diodes Compact energy efficient wide range of powers

One fixed line w lt10 nm tunability low volume cost of gt10 k$ per diode

External cavity QCLs Compact energy efficient gt50 mW line tunable over eg 600 nm 43 microm

Poor operation lt4 microm high cost gt50 k$

Syncrotron High intensity and covers the full spectrum

Very large and very expensive facility

Current mid-IR light sources


12

Requirements for mid-IR supercontinuum sources

1New fiber material to generate mid-IR light

2Pulsed laser sources (preferable with

wavelengths above 1700 nm)

3Single and multimode components to amplify the

pulsed laser to high ~10 kW power

4Components to collimate and shape mid-IR light

5Proving reliability and mass reducibility

6Building up the market for mid-IR SuperK sources


13

Fiber Material choice

bull Silica is opague above 24 microm

bull Soft glasses necessary

bull Glass choice dependent on several parameters

bull Dispersion loss and nonlinearity is most important

Spectrum consists of many short solitons with high peak power

Bandwidth not so important for pumping supercontinuum

By tailoring the design of the nonlinear fiber one can

control the output spectrum

MIR microscopy ndash Cancer diagnostics

bullInfrared hyperspectral imaging is simpler

than traditional staining methods

bullThe infrared data is less ambiguous and

thus requires less training to interpret

Conclusions

bull NKT wants to commercialize mid-IR supercontinuum

bull Requires soft-glass fibers

bull Requires pulsed lasers with wavelengths gt1700 nm

bull 2 microm lasers are very interesting but expensive

bull Hopefully this will change in the future
