Menhir-1550 Phase Noise at 250 MHz
Menhir-1550 GHz mode-locke laser

We invite you to peruse the new publication by Scott Diddams, et al. characterizing a fully phase stabilized 1 GHz repetition rate frequency comb centered at 1.56 µm. The Menhir-1550 Mode-Locked Laser is at the heart of the comb which demonstrated 438 mrad residual phase noise of the stabilized ƒCEO and 40.6 mrad of residual phase noise in ƒopt.

Vescent Photonics and COVID-19

I want you all to know that Vescent continues to operate. The safety and health of all of you and our employees is the most important issue in these times. Our R&D staff are designing and inventing from home offices, our production staff has setup assembly and test stations in their houses. Facility visits are kept to a minimum on split-shifts with sterilizations in between. Sales, marketing, and administration continue to operate remotely and will update all customers with any delays in deliverables. I could not be more proud of this team! Please do not hesitate to reach out to any Vescent personnel with questions; we are here to help. We all have science in our DNA, and science-guided planning will get us through these difficult times. As we design new quantum tools and products from our home offices and labs, we take comfort in the power of scientific thought. We will get through this!
