Where to Buy Infrared-to-visible Converters

ALPHALAS offers infrared-to-visible converters (visualizers) for detecting and visualizing IR radiation from CW and pulsed lasers, IR laser diodes and for revealing the transverse laser mode structure. They feature high sensitivity, high laser damage threshold due to the use of special durable ceramic-like material, coverage of wide spectral ranges 800 … 1150 nm and 1460 … 1650 nm, no need for activation with UV-light and no bleaching. The converters are mounted in black-anodized metal holders. The active surface diameter is 40 mm and has two active sides.

Kentek's VIEW-IT® infrared laser detectors feature a high efficiency laser sensitive material that provides an unlimited period of viewing for both pulsed and continuous wave lasers. These products require no charging, use no batteries or external power, yet provide continuous viewing of laser beam shapes.

VIEW-IT® Infrared Laser Detectors are stimulated by lasers with infrared wavelengths, 800–1,700 nm and emit a green color at 532 nm. The available configurations include discs, blocks, pocket cards, traditional wand and stand assemblies, flexible sheets with low-tack adhesive that you can cut to fit your unique application.

The Stuttgart Instruments Alpha is an ultrafast and fully wavelength-tunable frequency conversion system in an ultra-compact and completely passively stable system based on revolutionary parametric oscillator design which guarantees outstanding stability, reproducibility and shot-noise limited performance.

The revolutionary design of Stuttgart Instruments Alpha, characterized by outstanding low noise and passive long-term stability, is based on the fiber-feedback optical parametric oscillator (FFOPO) technology and results in outstanding performance and high flexibility at the same time.

The Alpha covers a gap-free rapid tunable spectral range from 700 nm to 20 µm wavelengths, while maintaining high output power up to the Watt-level with femto- or picosecond pulses at several MHz pulse repetition rates. It provides multiple simultaneously tunable outputs with a selectable bandwidth from a few to 100 cm-1. Shot-noise limited performance above 300 kHz, passive spectral stability (< 0.02 % rms) and wavelength-independent stable beam pointing (< 30 µrad) enable excellent sensitivity. In addition, each Alpha is equipped with a user-friendly ethernet and Wi-Fi interface and a matching graphical user interface (GUI) as well as easy to access API interfaces for e.g. LabView, Phyton, C++.

Typically, the Alpha is pumped by an ultra-low-noise Primus pump laser, which provides more than 8 W average output power at 1040 nm wavelength and 450 fs pulse duration at 42 MHz repetition rate. In addition, the Alpha can be operated with other pump lasers around 1 µm wavelength and enough power.

Due to our modular platform, the Alpha can be adapted and optimized for various applications and is particularly suited for spectroscopic applications requiring a robust and reliable tunable radiation with low noise.
