FREQUENCY STABILIZED Er-Yb LASER ON13C2H2 SATURATED ABSORPTIONS AT AROUND 1.54 μm
نویسندگان
چکیده
A novel and compact diode-pumped Er-Yb:glass laser, with single-frequency output power up to 20 mW in a wavelength range from 1531 nm to 1547 nm, was frequency stabilized with respect to sub-Doppler rovibrational transitions of C2H2. The laser frequency was locked to these molecular lines by means of the non-linear wavelengthmodulation spectroscopy technique. The relative frequency stability of the realized Er-Yb:glass-laser-(C2H2) optical standard is mainly dominated by a white frequency-noise contribution which sets an Allan deviation at a level of σy=7.5×10τ -1/2 for integration times in the range of 0.01 s<τ<100 s.

A novel and compact Er-Yb: glass laser was developed with single-frequency output power 10 mW in a wavelength range from 1531 to 1547 nm. The laser output was efficiently frequency doubled at 770.1 nm in a single-pass periodically poled lithium niobate waveguide and a second harmonic power in excess of 15 W was achieved, with an internal conversion efficiency of 220% W 1. This frequency-doubled...
متن کاملDevelopments of a space-borne stabilized laser for DECIGO and DPF
As a light source for the space gravitational wave detector DECIGO/DPF, we have developed space-borne frequency-stabilized lasers. The light source was an Yb-doped fiber laser with the wavelength of 1030nm. The frequency of the Yb-fiber laser was stabilized in reference to the saturated absorption of iodine molecules so as to suppress the frequency noise down to 1 Hz/rtHz at 1s. We will report ...

There is a growing interest in Near Infra-Red (NIR) emission originating from organic complexes of Ln cations. As a major impetus, biological tissues are considerably more transparent at these low energy wavelengths when compared to visible radiation, which facilitates deeper penetration of incident and emitted light. Furthermore, the long luminescence lifetimes of Ln complexes (eg. Yb, τrad ~ ...

We report the near to middle infrared luminescence and energy transfer process of Er(3+)/Yb(3+) co-doped fluorotellurite glasses under 980, 1550 and 800 nm excitations, respectively. Using a 980 nm laser diode pump, enhanced 1.5 and 2.7 μm emissions from Er(3+):I13/2→(4)I15/2 and I11/2→(4)I13/2 transitions are observed, in which Yb(3+) ions can increase pumping efficiency and be used as energy ...
