Ekspla's ANL SLM series electro-optically Q-switched nanosecond Nd:YAG lasers deliver up to 10 J per pulse with excellent stability. These systems are an excellent choice for many applications, including OPO, OPCPA or dye laser pumping, holography, LIF spectroscopy, remote sensing, optics testing and other tasks.

The innovative, diode‑pumped, self‑seeded master oscillator design results in Single Longitudinal Mode (SLM) output without the use of external expensive narrow linewidth seed diodes and cavity‑locking electronics. Unlike more common designs that use an unstable laser cavity, the stable master oscillator cavity produces a TEM₀₀ spatial mode output that results in excellent beam properties after the amplification stages. For tasks that require a smooth and as close as possible to the Gaussian beam profile, models with improved Gaussian fit are available.

ANL series linear amplifiers are cost effective solution for high energy nanosecond systems. Advanced beam shaping ensures smooth, without hot spots beam spatial profile at the laser output. Low light depolarization level allows high efficiency generation of up to 4th harmonic with optional build-in harmonic generators. The simple and field proven design ensures easy maintenance and reliable long-term operation of the ANL SLM series laser.

Angle-tuned non-linear crystals harmonic generators mounted in temperature stabilized heaters are used for second, third and fourth harmonic generation. Harmonic separation system is designed to ensure high spectral purity of radiation and direct it to the output ports. Harmonic generators can be integrated into laser head or placed outside laser head into auxiliary harmonic generator module. Output wavelength switching is done manually. Motorized wavelength switching is available by request.

The low jitter of the optical pulse with respect to the Q-switch triggering pulse allows the reliable synchronization between the laser and external equipment.

System control is available through control pad, USB and LAN interfaces (RS232 as optional). The system can be controlled from personal computer with supplied software for Windows operating system.
