Lasers
External Cavity Quantum Cascade Lasers (ECqcL™): Daylight Solutions has developed a suite of mid-infrared (mid-IR) tunable and fixed wavelength lasers to support today’s cutting-edge molecular detection and imaging applications. Our award-winning technology continues to drive growth in Daylight Solutions as commercial and research applications in the mid-IR expand. The molecules you care about have a color in the mid-IR. If it has a color, you can see it and if you can see it, we can detect it.

Introducing the New Enhanced-Stability CW-Mode Hop-Free Mid-IR Laser
Daylight Solutions is proud to introduce a new generation of mode hop-free (MHF) lasers. A complete redesign based on Finite Element Analysis (FEA) maximizes the lasers robustness with respect to vibrations and acoustic perturbations. A factor of 5 linewidth reduction (now <10 MHz) over our previous model and maximum stability are combined with new modulation capabilities to provide the ultimate tool for high-resolution spectroscopy and sensor development.
Our highest-performing tunable external cavity laser, the CW-MHF series provides continuous tuning over >30 cm-1 in the mid-IR. The combination of a narrow linewidth and excellent wavelength control allows for highly resolved spectral features in both survey and short, high-resolution scans. The two options for wavelength modulation over smaller ranges – either through a PZT or current modulation – have been improved, increasing and overlapping their response bandwidths.

Über Tuner™ Lasers
(Broadly Tunable)
Daylight Solutions is proud to announce the Über Tuner™ series of broadly tunable ECqcL™ (External Cavity quantum cascade Lasers). These pulsed lasers allow unprecedented access to high-brightness coherent light in the mid-IR. We now offer up to 250 cm-1 or 1.6 µm of tunability in a single package with narrow linewidth and easy tunability. The Über Tuner™ also offers higher powers – up to 400 mW and even more with the high-power option.
The broad tuning of the Über Tuner™ series lasers are just right for sensing and stand-off detection experiments as well as solid and liquid phase spectroscopy and imaging.

Tunable Laser (CW/Pulsed)
The Tunable CW/Pulsed ECqcL™ laser system is the laboratory work horse, providing the same broad tunability as the Tunable Pulsed system. However, in addition to Pulsed mode, the system also offers Continuous Wave (CW) operation.

Unicorn™ Lasers
(Fixed Wavelength)
The Unicorn™ fixed-wavelength laser is a stable source of light at a user-specified wavelength. High power, low frequency drift and a choice of wavelength make this laser an excellent source for imaging, illumination, LIDAR and DIAL, stand-off detection, OPO seeding, and detector calibration applications.

Tunable Laser (Pulsed)
The Tunable Pulsed ECqcL™ laser system provides the user with over 100 cm-1 of tunability in less than a second. This translates to tunability of 5% to 10% of the center wavelength. The platform offers adjustable pulse widths anywhere from 40 nsec to 500 nsec and pulse repetition frequencies (PRF) from 50 Hz to 100 kHz. The system operates at room temperature, requiring no external cooling.

Aries™ Lasers (High Power)
Daylight Solutions introduces the Aries™ series of high-power and fixed-wavelength lasers in the mid-IR. A modular “socket” approach allows for flexibility in performance including up to 10 W or 7 different simultaneous wavelengths. Proprietary beam combination techniques allow for collinear beam output for most wavelength combinations. Operated through a flexible interface, the Aries™ systems are all air-cooled and offer true cw and high-duty cycle pulsed operation. Designed for high-power applications such as optical fiber testing, stand-off detection, infrared countermeasures, scene generation, and machining, they offer rugged environmental specifications with the ability to operate over a large temperature range and withstand shaking and vibration.

Multi-function External Cavity Laser Controllers
The Daylight Solutions external cavity lasers provide a broad range of functionality. The performance of the laser is only as good as the controller and so we also provide a high-performance line of controllers. CW and pulsed operation modes are supported as well as tuning and fixed-wavelength performance. These controllers are low-noise current drive sources capable of pulses as short as 40 ns, repetition rates up to 1 MHz, and duty cycles as high as 50% (and CW operation). The controllers also integrate TEC control through a feedback loop for precise control of wavelength and power output. |

Thermal Laser Pointers
Our suite of “Thermal Laser Pointers” are ideally suited for applications where small, handheld, mid-infrared illumination or pointing is required. Available in wavelengths ranging from 3 to 20 µm, these devices can provide over 100 mW of output power in a package weighing less than 2 ounces.
