公司简介
Beyond Photonics is a private photonics design and advanced development company located in Boulder, on the Front Range of Colorado, a hotbed nation-wide of entrepreneurial and advanced photonics research and development activity. Located within minutes of three highly-relevant national labs (NOAA, NIST, and NCAR) and a major research university (CU/Boulder, and JILA specifically), as well as NREL in Golden CO, we have access to numerous associates for consultation and synergy. Lockheed Martin, Ball Aerospace, Google, and many other smaller specialized aerospace and high-tech companies are in the area as well.

COOLCARD
 | The CoolCard is a simple, easy-to-use laser beam display and “on-the-fly” evaluation technology available specifically for use with the ever-expanding field of eye-safe mid- and far-infrared laser sources, beyond the reach of competing technologies. Optimized for basic location and quick spatial-mode structure evaluation of IR beams in complex optical systems, the CoolCardTM II Laser Beamfinder is small, lightweight, and requires no low-light requirements or photonic “re-charging” like chemical phosphor cards do. Featuring the same great performance as its predecessor, the CoolCardTM II now features fast-rechargeable Li-Ion battery operation for more flexibility in the lab or the field (where AC power may not be easily available). The CoolCardTM II is hand-held, or can be post-mounted in two different orientations for “hands-free” use on the optical tabletop. The CoolCard is appropriate for use with:
|
Characteristics include:
Sensitive (3 mW/cm2), high spatial resolution display uses precision temperature stabilized liquid crystal
Sharper spatial resolution and greater wavelength range (0.8 µm-Far IR) compared to orange phosphor or cumbersome UV-charged passive cards
30 W/cm2 damage threshold—simple and inexpensive liquid crystal sensor replacement if damage does occur
Lightweight, hand-held design; post-mountable in “portrait” & “landscape” orientations for hands-free use
Same performance as our original CoolCardTM, but with enhanced flexibility for lab, factory floor, or field use
SWIFT CW FREQUENCY-TUNABLE SINGLE-FREQUENCY LASER
| The Swift is a compact, single-frequency, eye-safe diode-pumped laser optimized for use in coherent and direct detection lidar systems. Exhibiting high output power and < 10 kHz/ms short-term frequency jitter, the Swift is ideal for use as a master and local oscillator source in coherent lidar systems. Very fast and broad mode-hop-free frequency tuning enables next-generation spectroscopic applications like pollution monitoring and greenhouse gas measurements using differential absorption lidar techniques. This soon-to-be-released product will initially be offered using Tm,Ho:YLF operating across 2047-2059 nm wavelengths with multi-tens of GHz single-frequency tuning using an integral piezo actuator. The Swift capitalizes on Beyond Photonics’ decades of experience in the development and perfection of extremely stable single-frequency lasers. Other possible wavelengths include 1.06, 1.32, 1.5, 1.617, 1.645, 2.02, and 2.09 micron, with multi-nm set-ability across each central wavelength case. Please inquire about other wavelengths not listed. |
