technOlOgy prOducts lasers and diodes Frequency-converted diode lasers
Toptica has introduced its new SHG pro series of frequency-converted diode lasers, a novel CW system with an output power of 2W at 589nm. The new DL RFA SHG pro features a linewidth of less than 1MHz and a mode-hop free tuning range of more than 10GHz, and is thus well suited to laser cooling of sodium. It presents a stable and easy- to-use alternative to the intricate dye lasers used previously for this application, as these required frequent maintenance and water cooling. The DL RFA SHG pro is based on a tunable
external-cavity diode laser (eCDL) in Toptica’s proven pro design at 1178nm. The output of the eCDL is amplified within a novel polarisation- maintaining Raman fibre-amplifier (RFA), which preserves the spectral properties of the seed laser, particularly its narrow linewidth. Subsequently, the amplifier output is frequency-doubled in the SHG pro resonator to the target wavelength of 589nm. The system features an excellent beam profile and a high long-term power and frequency stability. The DL RFA SHG pro is ideally suited for
pulsed fibre laser for micromachining and more
Mobius Photonics has introduced its G1R3, a fibre-based, short-pulse, and high-repetition- rate laser system that can generate ultraviolet, green, or infrared output. The laser is intended for precision materials processing applications such as micromachining, solar cell manufacture and via drilling. It has been designed to quickly and efficiently ablate material while minimising the heat affected zone produced. The G1R3 is based on a master-oscillator,
fibre-power-amplifier (MOFPA) architecture. The standard system is available in three configurations: one that produces up to 30W of 1064nm output, a second that produces up to
ultrafast multipass amplifiers
Femtolasers has introduced the Femtopower X Pro CeP, the latest model in its family of ultrafast Ti:Sapphire multipass amplifiers. each Femtopower X is equipped with sub-μm accurate Beamwatch position detectors and Beamalign active beam pointing stabilisation. Femtopower X can be fully CeP stabilised
laser cooling applications and Bose-einstein condensation of sodium atoms, and is also of particular interest for mixed-atom systems. Special versions of the laser with output
powers up to 20W are also suitable for sodium- lidar, high-resolution microscopy, or laser guide star applications. The same technology can be transferred to wavelengths between 560 and 640nm (e.g. 583nm for laser cooling of erbium), or extended to frequency-quadrupled systems between 280 and 310nm (e.g. 285nm for laser cooling of magnesium).

by means of CeP3 technology. The Femtopower CeP amplifier line is proven to provide outstanding Ce-Phase stability over the longest period of time. With more than 50 systems installed in the most renowned laboratories, the Femtopower CeP has evolved to be an optimal light source for the most demanding application, including high harmonics and X-ray generation, attosecond science and ultrafast spectroscopy.

powerful dpss laser
18W at 532nm, and a third that produces up to 12W at 355nm. Mobius has also demonstrated power scaling of its G1 platform to reach higher average powers in the uV and green. In addition, the company holds a patent covering multi-head operation from a single system. using this technique, synchronised laser heads could provide higher system power output, or, if used separately, could allow parallel material processing. G1R3 systems provide tunable pulses 2-6ns
in duration, with repetition rates as high as 2MHz. Pulse widths remain consistent with changes in repetition rate, and the G1R3 laser produces diffraction-limited output over the range.

Midaz Lasers has launched its Flair-20 DPSS laser, offering 20W of IR at pulse repetition rates up to 500kHz. The company says that the short nanosecond pulse durations and high peak power capabilities of the Flare-20 laser are unmatched by fibre lasers. The linearly polarised beam and excellent beam quality enable efficient conversion to green and uV wavelengths. The laser features air-cooling, a compact
size, and a modular design to facilitate OeM integration. Applications for the laser include high speed laser marking and precision micromachining.

spectroscopy high sensitivity spectrometers
Avantes has introduced a new line of high sensitivity spectrometers, its AvaSpec SensLine range. The spectrometers are suitable for fluorescence spectroscopy and low light applications, and feature the company’s ultra-low stray light bench, a high speed uSB2 interface, and back-thinned CCD detectors with high quantum efficiency, which are available in 2048 x 16 or 2048 x 64 pixel formats. The AvaSpec-uLS2048x16-uSB2 model uses a
high speed detector for measurements in the uV to nIR range (200-1160nm). The effective detector height with 16 pixels of 14µm is 224µm, and the pixels are vertically binned. The advantages over

the current AvaSpec-uLS2048x14-uSB2 model are a faster integration time (min 0.91ms), improved dark noise, better etaloning, better anti-blooming and better dynamic range. Also newly introduced, the AvaSpec-
uLS2048x64-uSB2 model in the same Avaspec- Sensline range has an even higher detector height with 64 pixels of 14µm, vertically binned to an effective detector height of 900µm, resulting in a spectrometer that is four-times as sensitive as the alternative model. The AvaSpec SensLine will be available as of May
2011.
