Our specialists from HÜBNER Photonics will present the characteristics of state-of-the-art tunable CW OPO designs and outline examples of their use in colour center research.
In this webinar you will get a review of state-of-the-art CW OPO technology comprehensible even for the non-specialist, illustrated with recently published real-world experiments.
Widely Tunable lasers in Quantum Research: Novel Lasers for Novel Color Centers
Thanks for being a part of our succesfull webinar yeasterday
hosted by Physics World!
Questions are still coming in, and we love it!
Keep sending you questions, we are here for you.
Read a few of the questions from the webinar:
1. What’s the advantages of CW tunable laser over pulsed ones in single photon emitter research?
Answer from J. Sperling: This depends on whether the experiments are to be carried out in frequency domain (when a high frequency resolution is desired) or in time domain (when a high time resolution is desired). In frequency domain, continuous-wave (CW) tunable lasers allow to realize much narrower linewidths as compared to pulsed lasers. Simply speaking, this because the achievable narrowest spectral linewidth of a pulsed laser is related to the pulse length (by a Fourier-Transform relationship). For our CW tunable lasers, the linewidth typically is as narrow as 500 kHz in the visible spectral range.
2. Will this lasers work with semiconductors other than carbon group?
Answer from J. Sperling: We have shown the results on group IV colour defects to illustrate recent applications. However, the concept behind our tunable laser is quite general, so not limited to any particular type of sample.
3. Is it possible with the system to do a really coarse scanning over 100’s of nm?
Answer from J. Sperling: A clear yes! In fact, this is one of the key features of the concept behind our widely tunable lasers. Please don’t hesitate to contact us for further discussion of your wavelength requirments and tuning protocol.
4. What are the biggest challenges in commerzializing (cw) OPOs?
Answer from J. Sperling: Certainly, one of the biggest challenges is to qualify a suitable pump laser, since our widely tunable lasers require a high-performance continuous-wave and single-longitudinal-mode pump-laser source – like the Cobolt Samba 532 nm 1.5 W which we routinely use for pumping.
5. What about lab requirements and installation of C-WAVE OPO systems by HÜBNER Photonics?
Answer from J. Sperling: To ensure reliable operation within specifications, C-WAVE is to be installed on a vibration-isolated optical table and operated at stable (+/- 2°C) ambient temperature in the range 20-25 °C, at relative humidity in the range 10-85% with a stability better than +/- 10%, and under clear air conditions (free of dust). Installation will be carried out by one of our engineers. We typically schedule one day for installation and one day for in-depth user training on C-WAVE tunable laser Systems
