LQ215-D: Dual-Pulse Compact Nd:YAG Laser

LQ215-D: Dual-Pulse Nd:YAG Laser – Compact, Reliable, and High-Performance

Conventional dual-pulse lasers typically rely on either combining two separate laser systems or generating two successive nanosecond pulses from a single active element within one flash lamp discharge. While the first approach provides greater flexibility and performance, it also increases the system’s size and cost. The second method offers compactness and cost-efficiency, but compromises pulse energy, beam profile quality, stability, and pulse delay flexibility.

The LQ215-D is engineered to deliver the benefits of both approaches—without their drawbacks. It generates dual-pulse output using two independent cavities housed in a shared laser head. Both Nd:YAG rods are located in a single pump chamber and are driven by one flash lamp. This unified design allows for compact dimensions, cost-efficiency, and simple control of the dual-pulse parameters via a common power supply.

Its innovative and reliable optical configuration compensates for astigmatism and thermo-optical distortions, ensuring outstanding beam quality. All optical components operate well below their maximum rated loads, which significantly extends component lifespan and enhances long-term operational reliability. This means you can count on the LQ215-D for consistent, uninterrupted performance across daily and long-term experimental use—with minimal maintenance and no costly downtime.

The optical assembly is mounted on a rigid platform that is isolated from the housing using specially designed dampers, protecting cavity alignment from mechanical vibrations and housing-induced stresses.

Key laser components are thermally stabilized, and the vibration-resistant design ensures exceptional long-term output stability. Thanks to efficient thermostats, the system requires less than 10 minutes to reach full operating conditions.

Routine service is streamlined: the flash lamp offers a lifetime exceeding 50 million pulses, and its replacement process is quick and user-friendly. Notably, the flash lamp can be replaced without removing the laser head’s top cover, reducing the risk of contaminating internal optical components and further boosting system reliability.

A closed-loop water-to-air cooling system is integrated into a compact, single-phase power supply unit, which can be operated via PC or remote control for maximum user convenience.

 HARMONIC GENERATORS
The LQ215-D laser is equipped with built-in SHG, THG, and FHG in its standard configuration. Upon request, these harmonic generators can also be supplied as separate, stand-alone modules. FiHG is available exclusively as an external unit.

IR CONVERTERS
These compact devices integrate an OPO operating in NCPM mode and provide fixed-wavelength IR output ranging from 1.5 µm to 3.5 µm. They serve as convenient infrared sources for various applications.

POWER ATTENUATOR
A variable power attenuator can be added to the system. Depending on your requirements, it can be supplied either as a unit optimized for a single wavelength or as an achromatic attenuator designed to simultaneously attenuate all laser harmonics from 266 nm to 1064 nm

 ARTICULATED ARM
Certain applications demand fast and flexible laser beam delivery to the target or measurement area. While optical fibers can be used for low pulse energy transmission (typically 5–20 mJ), high-energy laser radiation requires a more robust solution. For this purpose, we offer an optional mirror-based articulated arm. To ensure minimal energy loss, the system uses specialized dielectric mirrors with high reflectivity at both 1064 nm and 532 nm wavelengths..
