Terahertz laser reaches 230mW power

Terahertz quantum cascade laser (QCL) shown in scanning electron microscope image by Wang, et al/AIP Advances

THE RECORD for continuous power output from a terahertz quantum cascade laser has been almost doubled to 230 milliWatts, researchers in China have reported. Terahertz wavelengths remain a relatively low-power part of the electromagnetic spectrum, lying between infrared and microwave.…

Fibre lasers suit optogenetics research

A combination of high average power and short pulsewidth are the main features of two new ultrafast fibre lasers from Coherent. This enables high intensity focusing for applications ranging from optogenetics research to commercial applications including scribing and rapid prototyping.…

Raman microspectroscope with multiple laser colours

CRAIC Technologies has added further laser wavelengths to its Apollo Raman microspectrometer, with blue, green, red, and infrared now available.  Used in conjunction with a light microscope, the Craic Apollo measures Raman spectra from samples or selected areas of large…

Lasers offer single longitudinal mode output

THE FIRST of their range of optically-pumped semiconductor lasers (OPSLs) to deliver single longitudinal mode (SLM) output, the two new Verdi G lasers from Coherent have a linewidth of less than 5MHz, which corresponds to a coherence length of tens…

Tunable blue laser is world first

THE WORLD’S first precision tunable blue laser operating at 461nm, the Vortex Plus Blue TLB-6802, has been launched by the New Focus division of Newport. This is the critical wavelength for the next generation of atomic clocks currently being built…

Eleven laser wavelengths in a single package

AVAILABLE in free-space or fibre-coupled configurations, the new line of Excelsior One lasers from Spectra-Physics deliver eleven different wavelengths and up to 500mW of average power. These plug-and-play lasers are intended for bioinstrumentation applications including flow cytometry, confocal microscopy, and…

New wavelengths for plug-and-play lasers

THE OBIS range of compact laser modules from Coherent has been extended with the addition of devices with outputs at 514nm and 552nm. Both deliver laser output power of 20mW, and says the company offer an optimum combination of beam…

Remote control for up to six Obis lasers

COHERENT’s Obis family of laser modules has just been expanded with the addition of Obis six-laser remote, which integrates the control of up to six separate lasers to make the range compliant with the latest CDRH (US Center for Devices and…
