Abstract:
In this paper the application of Wavelength Modulation (WM)
techniques to non-resonant saturation spectroscopy
in acetylene-filled
Hollow-Core Photonic Bandgap Fibres (HC-PBFs) and m
odulation-free
Laser Diode (LD) frequency stabilisation is investi
gated. In the first part
WM techniques are applied to non-resonant pump-prob
e saturation of
acetylene overtone rotational transitions in a HC-P
BF. A high-power DFB
chip-on-carrier mounted LD is used in conjunction w
ith a tuneable External
Cavity Laser (ECL) and the main saturation paramete
rs are characterized. In
the second part a novel feedback system to stabiliz
e the DFB emission
wavelength based on the WM saturation results is im
plemented.
Modulation-free locking of the DFB laser frequency
to the narrow linewidth
saturation feature is achieved for both constant an
d variable LD
temperatures
