フォトテクニカ List of Products and Services

The picoEmerald from the German company APE automatically overlaps extremely short pulse trains both temporally and spatially, providing three outputs: 1064 nm laser output, OPO signal, and OPO idler. Reliable pulse synchronization can be achieved, and fully automated control allows for hands-free operation. It produces high-quality picosecond pulses, making it ideal for CARS and microscopic spectroscopy. In addition to CARS and SRS, it is also perfect for applications in stimulated Raman microscopic spectroscopy and multimodal imaging, including multiphoton fluorescence and second harmonic generation. The wavelength can be tuned from 700 to 1950 nm, and even with changes, the two-color light pulses completely overlap both temporally and spatially.

• Other machine elements

It is possible to easily switch between output wavelengths of 515nm, 343nm, and 258nm, and simultaneous output of all three wavelengths is also possible. Used in the company's high-output femtosecond laser, PHAROS.

• Optical Measuring Instruments

The interferometer, pump & probe measurement optical system, and optical components of the correlator can be moved, positioned, and scanned at high speed. The scanning unit, designed with low mass and low friction, supports not only high precision and high-speed scanning but also a wide delay range. The scanning unit can be driven by the included controller or an external signal source. With the built-in position sensor, position information can be accurately obtained as an electrical signal. Changed to USB type only (2012).

Harmoni XX is a wavelength conversion modular system capable of generating harmonics from femtosecond and picosecond lasers and amplifiers with high efficiency. By incorporating a stepper motor, it enables high-precision wavelength adjustment, allowing for faster and easier wavelength switching, and has undergone repeated upgrades to accommodate a broader wavelength range, making it currently the most versatile in the market. By instantly switching optics, it can be used for a wide range of pulse widths from femtoseconds to picoseconds, and is designed to efficiently convert various laser powers, including Ti:sapphire lasers. Additionally, it can accommodate both frequency-variable fs/ps lasers and frequency-fixed fs/ps lasers. The optional quick conversion optics set is designed to flexibly switch between different types of lasers, with options for changing the wavelength range and switching the pulse width between fs and ps. When the laser wavelength is changed, it automatically adjusts the harmonic crystal to the optimal phase matching angle, consistently generating harmonics with the highest conversion efficiency.

High-performance aspherical lenses are used, allowing for the formation of high-quality micro spots. You can choose from three types of LD elements (Nichia, Sanyo, Sharp).

• Optical Measuring Instruments

This device, using MIIPS (Multiphoton Intrapulse Interference Phase Scan) technology, measures the spectral phase and pulse width of femtosecond lasers. In cases where there is spectral phase distortion, optimal pulse compression can be achieved through phase and amplitude modulation controlled by a PC. As a result, it is easy to obtain optimal transform-limited pulses at any measurement location. Therefore, it is ideal for applications such as the creation of arbitrary pulse sequences, experiments with dispersion compensation optical systems, and communication experiments.
