TOPTICA Photonics, a global leader in laser technology, continues to broaden its suite of high-performance photonics technologies with a lineup of innovative products designed to address the evolving needs of scientific, industrial, and research communities. Building on its legacy of delivering stable, reliable light sources and precision optical tools, the company’s latest additions span ultrafast fiber lasers, high-quality AR-coated diode sources, fiber optic isolation, frequency conversion systems, and interferometric measurement solutions.
FemtoFiber smart 780 - Compact Femtosecond Fiber Laser
The FemtoFiber smart 780 is an all-fiber femtosecond laser system that uses polarization-maintaining (PM) fiber technology and SAM mode-locking, which together ensure robust and reliable ultrafast pulse generation in a compact, turnkey format. The femtosecond-class pulse durations (<100 fs, ~85 fs typical) produce extremely short bursts of light, enabling high peak intensities ideal for nonlinear optical processes such as two-photon polymerization and terahertz generation. Its TEM00 beam mode and low beam divergence deliver high spatial beam quality, which implies precise focusing and consistency in demanding scientific and industrial applications. The all-fiber construction with integrated optics and electronics enhances stability and vibration resistance.
LD-1300-0100-AR-1 - AR-Coated Laser Diode
The LD-1300-0100-AR-1 is a free-space laser diode featuring a high-quality anti-reflection (AR) coating on the output facet. The AR coating suppresses reflections from the diode surface, which allows it to be used effectively in external-cavity configurations or integrated in narrow-linewidth laser systems. Operating in the near-infrared range (1120 nm - 1320 nm) with a CW output power of 0.1 W, this AR-coated diode is suitable for applications requiring a stable single-mode source as a seed or component in tunable laser assemblies. AR coating helps in exploiting the full gain spectrum of the diode when combined with external wavelength-selective elements.
SSR1250 - Single-Stage Optical Isolator
The SSR1250 is a Faraday optical isolator designed to protect laser sources by preventing unwanted back-reflected light from returning into the laser cavity. Back reflections can destabilize narrow-linewidth lasers or even damage diode emitters; the isolator’s high isolation (>35 dB minimum, >43 dB typical) ensures that backward propagating light is significantly attenuated, preserving coherence and stability of the source. With high transmission (>85 % typical) through the device, the isolator enables efficient forward propagation while mitigating feedback. The wavelength tunability around 1200 nm - 1300 nm makes it suitable for isolating lasers and optical systems operating in the near-IR band. The internal optical components are precisely angled to minimize stray reflections that could otherwise re-enter the laser.
SYST SHG pro - Optical Frequency Converter
The SYST SHG pro is an optical frequency conversion module that performs resonant second harmonic generation (SHG). It converts input light from 410 nm to 1600 nm to output light in the 205 nm - 800 nm range, enabling access to wavelengths not directly emitted by the primary laser source. The Pound-Drever-Hall locking scheme with automatic relock enhances stability by keeping the SHG cavity resonant with the input laser, which is critical for consistent conversion efficiency. Linearly polarized output with high polarization ratio (>100 : 1) supports efficient nonlinear interactions and downstream optical systems. The near-diffraction-limited beam quality and adjustable tuning ranges make this converter suitable for frequency-doubled applications such as optical clocks, Rydberg excitation experiments, and other precision optical measurements.
FPI-100-1500-1 - Fabry-Perot Interferometer
The FPI-100-1500-1 is part of the FPI 100 family of scanning Fabry-Perot interferometers and is designed for high-resolution wavelength analysis across the 1200 nm - 1700 nm spectral window. Fabry-Perot interferometers operate by multiple-beam interference between highly reflective mirrors, producing periodic transmission peaks separated by the free spectral range (FSR) - here 1 GHz - which translates to the ability to discriminate between closely spaced spectral features. With a typical frequency resolution of ~2 MHz, the FPI can resolve narrow laser modes and measure spectral characteristics of continuous-wave or stabilized lasers in telecom and precision spectroscopy applications. Interferometers with high finesse and controlled mirror sets enable accurate mode profiling and spectral diagnostics crucial for characterizing narrow linewidth optical sources.
Each of these products reinforces TOPTICA’s commitment to delivering stable, high-quality photonics solutions that integrate seamlessly into research labs, OEM platforms, and industrial environments. Designed for precision and reliability, the expanded portfolio supports a wide range of applications - from fundamental quantum research and spectroscopy to advanced imaging and metrology systems.
