Coming soon: C-WAVE GTR tunable laser, extended visible range

posted in: Allgemein | 0

HÜBNER Photonics offers 2 types of tunable lasers:

  • C-WAVE: CW tunable VIS (450 – 650 nm, > 200 mW) & NIR (900 – 1300 nm, > 400 mW)

  • Cobolt Odin™ : Mid-IR tunable, >7 kHz, wavelength selectable 2 – 5 µm, tunable up to 50 nm

  • Coming soon: C-WAVE GTR, single frequency CW tunable light Green-to-Red laser,
    500 nm – 740 nm, > 200 mW


Perfect for holography and high resolution spectroscopyC-WAVE is the tunable laser light source for continuous-wave (cw) emission in the visible and near-infrared wavelength range. Its technology is based on optical parametric oscillation (OPO) and it is fully computer controlled. Thus, it allows you to tune from blue to red and into the near-infrared without any change of dyes or optical components. This makes C-WAVE a flexible and user friendly laser for your applications.


Change the way you work

Visible, widely tunable, continuous-wave – for a long time this was equivalent to the handling of toxic dyes, to changing laser media or resonator mirrors or the restriction to narrow tuning ranges. C-WAVE is a solid state system
that has no consumable components such as dyes. The wavelength can be simply set at the computer. C-WAVE tunes itself automatically and guarantees superior beam quality as well as output stability across the whole tuning range – offering both high flexibility and precision at the same time. It offers you single frequency operation, narrow spectral linewidth and options for frequency stabilization combined with an unprecedented spectral coverage. Focus on your research, not on laser handling: C-WAVE helps you free your mind for your main tasks.

C-WAVE – tailored to your needs

Depending on the required output power level, C-WAVE is either pumped by an external single-frequency laser or comes with an integrated laser, making operation and application even easier for you.

Using software module AbsoluteLambda™ for C-WAVE enables precision and automatic frequency control with accuracy up to 2 MHz*.




“Widely tunable CW optical parametric oscillators: mastering the challenges posed in quantum technology research”

written by Korbinian Hens, Jaroslaw Sperling, Niklas Waasem and Ronja Gärtner, HÜBNER GmbH & Co. KG (Germany) together with Gunnar Elgcrona, Cobolt AB (Sweden) will be presented at the Moscone Center (Level 3 West) of SPIE Exhibition Photonics West in San Fransisco: Tuesday 4th at 6:00-8:00pm

Abstract Paper: “Widely tunable continuous wave (cw) OPO devices are gaining popularity due to their unprecedented wavelength coverage in the visible and near infrared spectral range. While particular interest has been generated in the realm of experimental quantum technology research, the experimental demands are typically challenging the device performance. In this context, we present the characteristics of novel state-of-the-art tunable cw OPO designs and discuss several tuning schemes based on internal and/or external frequency selection and stabilization, tailored to meet sophisticated experimental requirements. Recent experimental data on single-photon emitters is presented in an illustrative fashion.”

Conference attendees are invited to attend the LASE poster session on Tuesday evening. Come view the posters, enjoy light refreshments, ask questions, and network with colleagues in your field.
