High-resolution spectroscopy of exotic silver with a CW OPO injection-seeded PDA

Khwairakpam² , Bram van den Borne³ , Michael Heines³ , Ágota Koszorús³ , Katerina Chrysalidis⁴, Ruben P. de Groote³,⁵, Bruce Marsh⁴, Korbinian Hens¹ , and Klaus Wendt⁶ for the CRIS-Collaboration — ¹Division HÜBNER Photonics, HÜBNER GmbH Co KG, Germany — ² Istituto Nazionale di Fisica Nucleare LNL, Italy — ³KU Leuven, Belgium — ⁴CERN, Switzerland — ⁵University of Jyväskylä, Finland — ⁶ Johannes Gutenberg Universität, Germany

Short-lived radioisotopes are of special interest for nuclear structure studies, as their characteristic provide valuable reference points for theoretical predictions far from stability. By using lasers, hyperfine transitions can be accessed, allowing direct measurement of nuclear observables. For such high-resolution spectroscopy, narrow-band pulsed lasers can be created by the pulsed amplification of a cw seed laser, keeping the amplifier’s high power and short time profile whilst acquiring the seeder’s spectral properties. Spectroscopy on exotic Ag was performed at the CRIS experiment at CERN. A tunable CW single-mode OPO was employed as injection-seed for a two-stage pulsed dye amplifier. e hyperfine splitting of the ground-state ² S_1/2 to the level ² P^O_3/2 was measured and the hyperfine coupling constants were determined. For this work, ¹¹¹,¹¹⁷Ag are presented, showcasing this laser system’s applicability for future high-resolution spectroscopy studies.

The proprietary fiber laser technology of VALO Innovations delivers market-unique short pulse performance. With pulse lengths of <50 fs and peak powers of >2 MW from compact and stable turn-key systems, and with fully integrated group-velocity dispersion pre-compensation control, the VALO Innovations fs fiber lasers bring very attractive features for applications in bioimaging, spectroscopy and micro-machining.

VALO Innovations GmbH will remain in Hannover and the VALO fs lasers will become a new product-line adding to HÜBNER Photonics’ broad portfolio of high performance laser products including the Cobolt product-line of single-frequency CW and Q-switched ns lasers, the C-FLEX laser combiners and the award-winning widely tunable single-frequency CW laser; C-WAVE.

“We are extremely excited to add the unique fs laser technology of VALO Innovations to our group. Their innovative mind-set, engineering capabilities and customer orientation make a perfect fit with us and we are very much looking forward to being able to offer our customers these highly complementary products in the short pulse regimes, with the performance, quality and support they have become accustom to receiving from us” says Head of HÜBNER Photonics, Dr. Håkan Karlsson.

Dr. Oliver Prochnow, co-founder and CEO of VALO Innovations is equally excited stating “It’s an amazing step and a great pleasure to be a part of such a strong reputable group such as HÜBNER Photonics. We both share the same views and we are looking forward to the opportunity of growing the VALO laser product portfolio and accelerating our market access with the support of existing technical and sales competences of HÜBNER Photonics and its partners”.

Press release – S&I qualifies the C-WAVE for use with TriVista spectrometer

S&I qualifies the C-WAVE tunable laser for use with their TriVista spectrometer

The combination of a widely tunable spectrometer and widely tunable laser advances resonant Raman spectroscopy

WARSTEIN, April 29, 2021: S&I Spectroscopy & Imaging GmbH, a developer of high-performance spectrometers, today announced it has qualified the C-WAVE tunable laser from HÜBNER Photonics for use with their TriVista spectrometer system. The combination of the C-WAVE widely tunable continuous-wave (cw) single frequency lasers (covering wavelengths from 450 nm up to 3.5 µm) with the triple-grating spectrometer TriVista is expected to become a new standard for resonance Raman spectroscopy and microscopy.

“We are delighted to work with a renowned partner like S&I in order to help them advance the state of the art in resonance Raman spectrometers. The TriVista spectrometer with its exceptional resolution, sensitivity, and linearity over wide spectral ranges is a powerful instrument that revealed deep insights about the C-WAVE’s spectral performance. We are thankful for the excellent collaboration and the valuable feedback,” says Korbinian Hens, Chief Operating Officer and R&D Manager at HÜBNER Photonics Kassel.

“The combination of the TriVista spectrometer with the C-WAVE is a powerful and flexible solution for resonant spectroscopy methods, especially for the challenging low-frequency Raman range < 10 cm-1. The extremely narrow linewidth and very stable emission frequency of the C-WAVE paired with its outstanding spectral purity allows recording impressive Raman spectra: we were able to measure low frequency Raman bands at or below 5 cm-1 from the excitation wavelength even without filtering the excitation beam,” says Nils Timpe, Head of Sales at S&I.

For applications in Raman spectroscopy, most tunable lasers require elaborative filtering to suppress unwanted amplified spontaneous emission (ASE) which can cover the weak Raman signals. Cleaning up the laser’s emission spectrum can be challenging especially for the low-frequency Raman range close to the excitation wavelength. During qualification, the C-WAVE revealed no detectable ASE. Figure 1 shows a Raman spectrum of an L-Cystin sample recorded at excitation wavelengths of 455 nm and 520 nm.

Figure 1: Raman spectra of L-Cystine recorded at two excitation wavelengths employing the TriVista spectrometer from S&I with triple monochromator system (Teledyne Princeton Instruments Spectra Pro 750 HRS) in the high-resolution, subtractive mode with three gratings (2400 lines/mm), Princeton Instruments Pixis:256E detector cooled to -70°C (-90°F), and C-WAVE tunable laser from HÜBNER Photonics as the excitation source. The L-Cystin sample placed in a glass cuvette was measured in a non-confocal macro chamber at an incidence-angle of 60° to the resulting Raman beam path. The C-WAVE laser and TriVista spectrometer are shown to the right.

“The integration of the C-WAVE with our TriVista system went smoothly. The user-friendly software and automatic tuning functionality made it easy to control the laser. It is impressive that the C-WAVE’s beam position and pointing is so stable even after tuning over a range of 200 nm across the visible spectrum. This fact in combination with the perfect Gaussian beam profile reduces the complexity of the optical setup and helps speed up experimental work,” says Jannick Saatz, R&D engineer at S&I.
