Short-wavelength soft-x-ray laser pumped in double-pulse single-beam non-normal incidence

2010

We demonstrated a $7.36$ nm Ni-like samarium soft-x-ray laser, pumped by $36$ J of a neodymium:glass chirped-pulse amplification laser. Double-pulse single-beam non-normal-incidence pumping was applied for efficient soft-x-ray laser generation. In this case, the applied technique included a single-optic focusing geometry for large beam diameters, a single-pass grating compressor, traveling-wave tuning capability, and an optimized high-energy laser double pulse. This scheme has the potential for even shorter-wavelength soft-x-ray laser pumping.

Passive optical resonator for OSQAR LSW experiment

2016

This paper treats the issue of locking a solid state laser, pumped by high power diodes (Verdi V5), to a twenty meter long optical resonator for OSQAR LSW - light shining through the wall, dark matter search experiment. In this paper the optical design and a possible locking scheme are presented. The environmental conditions in SM18 testing hall at CERN, where OSQAR experiment is based, are discussed. The main focus is put on the vibration analysis, cavity transversal modes behaviour, possible clipping in the anticryostat of LHC – Large Hadron Collider magnet bore and locking loop parameters required for future experimental testing. The expected finesse of resonator will be presented and di…

Development of a laser ion source at IGISOL

2005

FURIOS, the Fast Universal laser IOn Source, is under development at the IGISOL (Ion Guide Isotope Separator On-Line) mass separator facility in Jyvaskyla, Finland. This new laser ion source will combine a state-of-the-art solid state laser system together with a dye laser system, for the selective and efficient production of exotic radioactive species without compromising the universality and fast release inherent in the IGISOL system. The motivation for, and development of, this ion source is discussed in relation to the programme of research ongoing at this mass separator facility.

Phase-conjugate emission of a two-mirror solid state laser

2002

We show that phase conjugation strongly contributes to the emission of a solid state laser in a two-mirror (Fabry-Perot) resonator , enabling dynamic correction of thermal lensing . Full correction of thermal effects is reached by vector phase conjugation .

Intracavity Frequency Doubling and Difference Frequency Mixing for Pulsed ns Ti:Sapphire Laser Systems at On-Line Radioactive Ion Beam Facilities

2015

Intra-cavity second harmonic generation of a Titanium:sapphire (Ti:sa) laser system has been used to improve the conversion efficiency to the second harmonic. Over the course of several experiments performance data spanning the whole wavelength range of a Ti:sa has been collected, which may be used as a guideline for future experiments. An average output power of up to 3.7 W was achieved, resulting in a conversion efficiency of >75 % to the second harmonic. A wavelength coverage from 340-525 nm has been demonstrated. To extend the wavelength range of the solid state laser system, difference frequency mixing has been applied to the intra-cavity doubled light and the fundamental output of a s…

Piranilidena atvasinājumu optiskās un pastiprinātas spontānās emisijas īpašības PVK matricā

2015

Organiskie materiāli ir daudzsološi dažādiem moderniem pielietojumiem, tai skaitā optiski ierosinātiem organiskajiem cietvielu lāzeriem, kuriem vajadzīgi materiāli ar augstu pastiprināšanās koeficientu un zemām ierosmes enerģijām. Vairumā organisko sistēmu šie parametri ir limitēti krāsvielu molekulu kristalizācijas dēļ. Tādēļ savienojumi ar samazinātu kristalizēšanos būtu ļoti noderīgi. Šajā darbā tika pētītas plānās kārtiņas ar jauniem plaši zināmās krāsvielas DCM atvasinājumiem PVK polimēra matricā dažādās koncentrācijās. Kārtiņām tika uzņemti fotoluminiscences spektri un veikti pastiprinātas spontānās emisijas (PSE) mērījumi. Tika novērota spēcīga koncentrācijas ietekme uz emisijas spek…
