Let us help select the right configuration for you!

We have been working with QLI for ~10 years, and their dedication to customers, exceptional support and service, and willingness to customize a laser has been demonstrated many times. For instance, a customer stuck with an unforgiving integration space to squeeze a 100 mJ-class laser into. QLI was able to easily modify the Q2HE package to fit their existing space, saving a redesign of the customer’s system. In another instance, a customer was having an unexpected issue with their laser, and QLI made immediate arrangements to visit their facility. After observing the laser’s excessively harsh operating environment, QLI redesigned the laser for their application to enhance its robustness and long-term performance in such conditions.

QLI is more than just a laser manufacturer. They’re a partner. They understand that every customer is unique and are committed to providing configurable solutions tailored to your specific needs. They’re there when you need them and ready to go the extra mile to ensure you’re getting the most out of their products.

Q-DOUBLE Series

The Q-DOUBLE series is a DPSS, air-cooled, q-switched laser at 1064 or 1053 nm, designed to produce two pulses with variable temporal separation for PIV, LIBS, and other applications. The Q-DOUBLE can be configured for up to 160 mJ pulse energy @ 10 Hz or up to 40 mJ @ 100 Hz. The innovative laser design integrates all electronics (except power adapter) into the housing, resulting in a compact, user-friendly, turnkey, and air-cooled (water-free) system requiring little maintenance. User-friendly web-based GUI allows remote monitoring, control, and support from any computer or even a smartphone. Optional add-ons include built-in 2nd, 3rd, or 4th harmonic generator, built-in attenuator, energy monitor, and optional short cavity version.

Q-SHIFT Series

The Q-SHIFT series of Q-switched DPSS lasers is designed for researchers and application specialists working in micromachining, dermatology, LIDAR, time-resolved laser spectroscopy, and LIBS applications. With its built-in nonlinear wavelength conversion stage, this series can produce unconventional DPSS wavelengths: 1163, 1177, 1300, 1317, 1551 & 1571 nm. The optional harmonics generator can generate up to the 4th harmonic for each fundamental wavelength, providing even more versatility. This series can produce up to 40mJ/1W @ 1163nm with up to 100Hz repetition rate.

Q-Spark

The Q-SPARK series is an air-cooled, diode-pumped, Q-switched laser designed for researchers and application specialists working with ablation, LIDAR, remote sensing, and LIBS applications. The laser produces sub-nanosecond or nanosecond pulses with peak power up to 20 MW and pulse energies up to 20 mJ, making it ideal for a wide range of applications. With a short pulse (<800 ps to <2 ns), compact air-cooled package, and innovative water-free laser crystal end-pumping technology, the Q-SPARK series delivers high-quality, low divergence, Gaussian-like laser beams.

Q-TUNE-G Series

The Q-TUNE-G series is a highly advanced air-cooled, tunable wavelength laser. It offers hands-free, automated tuning from 680 to 2300 nm, delivering up to 11 mJ pulse energy in the near-IR range. With a <10 cm-¹ linewidth and up to 100 Hz pulse repetition rate, it’s ideal for photoacoustic imaging, non-linear spectroscopy, and more.
