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.

Hamamatsu Photonics 50mW CW Single Chip Laser

Hamamatsu Photonics introduce a brand new 50mW CW single chip laser diode, the L11336. This new diode is a lateral single mode type, with an emitting area of 5µm and a centre wavelength of 1205nm.

This new laser diode adds to Hamamatsu’s increasing range of single chip laser diodes, available at wavelengths from 685nm to 1205nm. The L11336 features very long lifetime characteristics, and is available in 5.6mm and 9mm diameter CD packages, as well as side-out and head-out OHS packages.

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. Stacked bar arrays (with up to several Kilowatts output power), fibre-optic coupling and a choice of other wavelength laser diodes are all available to specific customer request.

QCL Series Low Noise Quantum Cascade Laser Driver

The QCL Series Low Noise Drivers include patented circuitry ideal for driving Quantum Cascade Lasers (QCLs). Available in models up to 2A with low RMS noise (less than 0.7 µA for QCL1000).

An onboard Current Setpoint trimpot allows a DC bias to be set. Its signal sums with a remote Analog Input signal that can be negative or positive.

Safety: An onboard trimpot sets the current limit. Brownout, reverse voltage, and overvoltage protection isolate the QCL from power supply failures. An Overtemp Fault signal minimizes the chance of failure due to overheated electronics. Onboard or remote Enable controls when current can flow to the QCL. Once enabled, there is a 1.5 second delay and a slow-start ramp to safely power on the QCL. LED status indicators for Power ON, Enable, and FAULT are on the front panel. Status signals on the output connector can also drive external LEDs.

This OEM controller can be integrated into field deployed systems or used on a benchtop.

It provides NIST-traceable accuracy and precision for measuring CW and kHz pulsed laser beams from UV to far IR. Scanning-slit technology makes it easy because it can measure even high power beams without the need for complicated attenuation schemes.
