Hamamatsu Photonics 20 Milliwatt Single Mode CW Laser Diode

Hamamatsu Photonics introduce a brand new 20mW CW laser diode, the LC0293, with a peak emission wavelength of 763nm and is a lateral single mode type, with an emission area of just 1µm x 5µm.

Designed specifically for use in oxygen monitoring applications, the LC0293 uses a distributed feedback (DFB) structure, which allows for a very narrow line width; a maximum spectral radiation half bandwidth of just 1 picometer. The new diode also features very long lifetime characteristics, and is available in a 9mm CD package. This new single mode laser diode will be of interest for any application where a reliable light source for oxygen monitoring is required.

Hamamatsu also offer a range of laser bar devices, supplied either as bare diodes, or provided as a module, with CW powers up to 60 Watts per bar and a choice of water cooling, peltier cooling or Hamamatsu’s patented funryu cooling technology.

Ultra-Low-Noise Single Photon Detector

The SQLightSensor is a ultra low noise near infrared NIR Single Photon Detector based on a Geiger-mode InGaAs avalanche photodiode and a internal thermoelectrically cooler.

The Single Photon Detector is ideal for the most demanding scientific, defence and industrial applications, such as single photon counting, spectroscopy, microscopy, fluoresence, eye-safe laser range finder and LIDAR, and quantum cryptography.

The single photon counter includes a Geiger-mode InGaAs avalanche photodiode (APD) and a thermoelectrically cooler that ensures high detection efficiency, low dark count, high speed, and low jitter. Thanks to its outstanding high level detection sensitivity the single photon counter provides significant benefit over existing detectors.

In addition the photon counter provides plug-and-play Personal Computer connections via the USB interface which enable to easily adjust the detection efficiency, and tune the gate width and delay.
