Continuous tuning over 80 nm is demonstrated for the anti-Stokes wave generated in an optical parametric oscillator (OPO) based on a birefringent photonic crystal fiber pumped by a CW Ytterbium-doped fiber laser tuned around 1.05 μm (within 4 nm...

Aldosterone Signals the Onset of Depressive Behaviour in a Female Rat Model of Depression along with SSRI Treatment Resistance.

Neuroendocrinology

PMID: 25968351
Neuroendocrinology. 2015;102(4):274-287. doi: 10.1159/000431152. Epub 2015 May 09.

Depression is a serious condition that occurs more frequently in women and is often associated with treatment resistance. The main hypotheses of this study are that (a) aldosterone is an early marker of depression onset and (b) a tryptophan...

Spectral broadening in Raman fiber lasers.

Optics letters

Babin SA, Churkin DV, Ismagulov AE, Kablukov SI, Podivilov EV.
PMID: 17001382
Opt Lett. 2006 Oct 15;31(20):3007-9. doi: 10.1364/ol.31.003007.

We present an analytical theory based on wave kinetic equations that describes a Raman fiber laser (RFL) generation spectrum. It is shown both theoretically and experimentally that the quasi-degenerate four-wave mixing between different longitudinal modes is the main broadening...

Solid phase extraction and HPLC determination of veterinary pharmaceuticals in wastewater.

Talanta

Babić S, Asperger D, Mutavdzić D, Horvat AJ, Kastelan-Macan M.
PMID: 18970832
Talanta. 2006 Nov 15;70(4):732-8. doi: 10.1016/j.talanta.2006.07.003. Epub 2006 Aug 22.

This work focuses on the application of SPE-HPLC analysis of important veterinary pharmaceuticals from different classes in highly complex wastewater matrix. The pharmaceutical investigated included three sulfonamides (sulfamethazine, sulfadiazine and sulfaguanidine), a sulfonamide synergist (trimethoprim), a tetracycline (oxytetracycline), a...

Experimental demonstration of mode structure in ultralong Raman fiber lasers.

Optics letters

Babin SA, Karalekas V, Harper P, Podivilov EV, Mezentsev VK, Ania-Castañón JD, Turitsyn SK.
PMID: 17410260
Opt Lett. 2007 May 01;32(9):1135-7. doi: 10.1364/ol.32.001135.

We present the first experimental demonstration of a resolvable mode structure with spacing c/2nL in the RF spectra of ultralong Raman fiber lasers. The longest ever demonstrated laser cavity (L=84 km), RF peaks of ~100 Hz width and spacing...

Mechanism of mode coupling in multicore fiber lasers.

Optics letters

Kurkov AS, Babin SA, Lobach IA, Kablukov SI.
PMID: 18157258
Opt Lett. 2008 Jan 01;33(1):61-3. doi: 10.1364/ol.33.000061.

We present what is believed to be the first experimental demonstration of a new mechanism of mode coupling in multicore fibers (MCFs) based on their indirect interaction inside the fiber via intermediate mode, analogous to the Bragg mode, which...

All-fiber widely tunable Raman fiber laser with controlled output spectrum.

Optics express

Babin SA, Churkin DV, Kablukov SI, Rybakov MA, Vlasov AA.
PMID: 19547175
Opt Express. 2007 Jun 25;15(13):8438-43. doi: 10.1364/oe.15.008438.

A simple all-fiber widely tunable phosphosilicate Raman fiber laser (RFL) of high efficiency has been developed. The laser has more than 50 nm tuning range, and generates up to 3.2 W of output power with 72% maximum slope efficiency....

Broad-range self-sweeping of a narrow-line self-pulsing Yb-doped fiber laser.

Optics express

Lobach IA, Kablukov SI, Podivilov EV, Babin SA.
PMID: 21935130
Opt Express. 2011 Aug 29;19(18):17632-40. doi: 10.1364/OE.19.017632.

The effect of broad-range (16 nm) self-sweeping of a narrow-line (less than 1 pm) Yb-doped fiber laser has been demonstrated experimentally. It is found that the effect arises from the self-sustained relaxation oscillations. As a result, the sweeping rate...

Antenatal embolization of a large placental chorioangioma: a case report.

Journal of medical case reports

Babic I, Tulbah M, Kurdi W.
PMID: 22759589

INTRODUCTION: A chorioangioma is the most common benign tumor of the placenta. The majority of pregnancies with chorioangiomas are asymptomatic. Pregnancies with large chorioangiomas are associated with maternal and fetal complications, such as growth restriction, cardiomegaly, congestive heart failure,...

Raman gain saturation at high pump and Stokes powers.
