HÜBNER Photonics

The broad spectral coverage of diode lasers combined with a compact form factor, direct modulation capability (up to 150 MHz) and built-in spectral filters. Ideal for applications in high-resolution bioimaging, flow cytometry, optogenetics and quantum technologies.

All Cobolt diode lasers are manufactured using patented HTCure technology. The resulting compact housings and robust optical assemblies provide a very high level of resistance to varying environmental conditions and exceptional reliability. Lasers built with HTCure have been proven to withstand repeated 60G mechanical shocks during operation without any signs of performance degradation.

Characterized by emission with very narrow linewidths (<1 MHz in the specification and <100 kHz typically), low phase noise <0.1% RMS and an ideal diffraction-limited beam TEM00 . Unlike multimode lasers, which emit over a wide spectrum, single-frequency lasers emit at a specific, well-defined frequency, resulting in a very clean and monochromatic output.

Narrow spectrum width is of paramount importance for scientific and industrial applications requiring precision and accuracy. It enables high-resolution spectroscopy, interferometry, and frequency measurements, enabling the study of minute aspects of atomic and molecular spectra, precise measurements, and the development of stable and coherent light sources. In addition, in areas such as optical communications, it minimizes crosstalk between channels, ensuring reliable data transmission and maximum spectral efficiency.

The laser resonators incorporate frequency-selective optics that stabilize the resonator and prevent all but one of the longitudinal and transverse laser modes from being amplified in the generator, resulting in extremely stable single-frequency SF emission and an ideal diffraction-limited beam.

By combining advanced resonator designs, both standing wave and ring resonators, with a thermo-mechanically stable platform, active temperature control of the entire resonator, and secure mounting of miniature precision optics, Cobolt's DPSS (DPL) lasers provide stable single-frequency or single-spacing operation over the entire laser lifetime and over a wide range of operating conditions.

Lasers with stable SLM (single longitudinal mode) characteristic and narrow linewidth, exceptional spectral accuracy, built-in optical isolator and integrated electronics. The lasers in this series are the ideal choice for all challenging Raman spectroscopy applications.

It consists of diode-pumped SLM lasers (DPL) as well as frequency-locked diode stabilized lasers (NLD). The DPL lasers are single-frequency lasers with linewidths <1 MHz, and the NLD lasers are narrowband lasers with linewidths of several 10 pm. All products in the series have an integrated optical isolator and short pass filter as standard, ensuring immunity to optical feedback. The laser can be easily connected to the fiber directly on the laser housing (SM/PM or multimode).

They consist of passively gain-switchable diode-pumped solid-state lasers (DPSSL) or diode-pumped nanosecond lasers (DPL). The laser-amplified medium is pumped by a high-power semiconductor laser. The energy and pulse length are set by the optical design of the laser.

Cobolt's gain-modulated lasers are compact ring-cavity lasers by design, which ensures a stable pulse train with low jitter and excellent beam quality even at kHz repetition rates. Thus, Cobolt QM lasers combine the compact format and cost-effective design of passive QM lasers with high optical pulse characteristics that are typically only achieved with active QM lasers.

A compact laser head with multiple lasers built inside and collimated into one permanently aligned output beam, thus creating the appearance of a single laser operating at multiple wavelengths. The multi-line laser is therefore very attractive as an extremely compact and easy-to-use solution for adding additional features and wavelengths to the system.

Built with HTCure technology to ensure reliability and superior performance throughout the life of the laser. The multi-line laser provides up to 4 wavelengths in one compact housing with integrated electronics.

The ultrafast fiber laser series is uniquely designed to deliver the shortest femtosecond pulses and highest peak power that can be achieved with a compact off-the-shelf solution. Pulse durations <50 fs are achieved with new fiber laser-based technology.

Clear and ultra-short pulses, combined with computer-controlled group velocity dispersion pre-compensation, allow users to achieve maximum peak power exactly where it is needed, making the lasers ideal for use in multiphoton imaging, advanced spectroscopy and many other applications.

The technology is based on optical parametric generation (OPO) and is fully computer controlled. Thus, it allows tuning from the blue to the red region of the spectrum and to the near-infrared region without changing dyes or optical components. This makes the C-WAVE a flexible and convenient laser for use in a variety of applications.

The Cobolt Odin series is an ultra-compact industrial mid-IR source based on a fully encapsulated tunable optical parametric oscillator (OPO) with an integrated pump laser. Periodically poled nonlinear optical crystals are used for efficient and spectrally versatile generation of mid-IR radiation. It is available with fixed center wavelengths of 3264 nm, 3431 nm and 4330 nm tunable to 50 nm.

Terahertz imaging systems represent a revolutionary technological innovation in imaging, using terahertz radiation to visualize and examine objects and structures that are otherwise hidden from view.

They enable non-destructive testing and analysis in a wide range of applications, from safety and quality control to medical diagnostics and cultural heritage preservation. Using the distinctive absorption and reflection characteristics of different materials at terahertz frequencies, these devices allow researchers, engineers and medical professionals to identify hidden defects, inspect materials for anomalies and even visualize biological tissues and structures in minute detail.
