Products & Services
CHANGE THE COLOR OF LIGHT TO EXPAND YOUR POSSIBILITIES!
GWU-LT’s dedicated service helps to find the best core components for your application. GWU-LT is a well-known manufacturer of tunable laser devices as well as an expert for laser and optical components. A wide knowledge and in-field experience can be shared to the advantage of our customers.
Our tunable nanosecond laser devices have been continuously improved and refined, always in line with our philosophy of offering robust laser systems with the highest level of reliability. Today, our 5th and 6th generation of OPOs are matured tunable nanosecond laser devices, providing high-energy, pulsed light from the deep-UV to the mid-IR spectral range. Our sophisticated optical and mechanical design and our soft pumping scheme ensure excellent performance and longest lifetime. With all-solid-state laser technology the GWU-OPOs are suitable even for the most demanding applications in science and industry!
Tunable Lasers for Photoacoustic Imaging
GWU’s new generation of tunable Laser-OPO systems has been designed with the focus on photoacoustic applications. All-integrated platforms ensure maximum reliability and best usability. The tuning range addresses the absorption of the most important chromophores in the near IR. Fast wavelength tuning and energy monitoring in real-time reduce measurement time and provide full laser beam information. Fiber coupling ensures convenient beam delivery.
Watch the short video, where the exceptional shot-to-shot wavelength switching capabilities of our Laser-OPO systems is demonstrated. Leveraging our proprietary fast-tuning technology, seamless, high-speed wavelength transitions across the full spectral tuning range are enabled, without compromising stability or precision.
Ultrafast Pulses on Demand
Flexible pulse picking for pico- and femtosecond lasers.
The pulse selector option for our UHG-Series offers a Bragg cell for the highest output powers and good contrast ratio. The system is suitable for femtosecond and picosecond pulses with high input powers, without requiring any attenuation. Integral pulse selecting is possible from single shot to 40 MHz, cobined with adjustable contrast ratio by convenient software control.
The UHG Pulse Selector is either available as standalone version or it can be integrated in our Harmonic Generator, where it is positioned before all harmonic stages to offer all features and wide wavelength coverage in a single compact housing. The UHG series is a flexible system suitable for a variety of scientific applications requiring access to a wide spectrum of femtosecond or picosecond laser pulses.
High Energy Pulsed Lasers
The primoScan OPO Series are high-energy frequency conversion devices for pulsed Nd:YAG-Lasers, continuously tunable from Deep-UV to Mid-IR for versatile applications. An innovative automation concept allows for fast wavelength switching covering the entire tuning range with high precision. With the DPSS version, high repetition rates up to 100 Hz are supported.
The modular design allows for the use of different pump lasers, scaling of energy, and expansion of the wavelength range.
Highest Energy, Tunable NIR - primoScan 532
GWU-Lasertechnik expands the primoScan product line with the 532 nm-pumped version. The primoScan 532 is delivering market-leading, tunable near-infrared (NIR) output energy with exceptional ultra-low divergence (ULD) beam quality. The fast-switching capability allows for changing the wavelength across the entire range with <100 ms shifting time. The modular design of the primoScan ensures optimum versatility for scaling of energy, and expansion of the wavelength range in almost any application.
The OPO’s tuning range is covering 655 nm to 2700 nm. Paired with optional second harmonic generation (SHG), it can be extended to the UV and visible, providing tunable 330 nm to 520 nm output.
