PRODUCT UPDATE Laser and diodes Fidelity fibre laser


AeroPulse picosecond lasers NKT Photonics has released the AeroPulse line of high power picosecond lasers – a portfolio of industrial-grade mode-locked fibre lasers based on NKT’s photonics crystal fibre platform. The line is designed for applications within semiconductor inspection, bioimaging and material processing.


The AeroPulse lasers have up to 40W


average power and 5-20ps pulse length. The system can be operated 24/7, maintenance free, and can be monitored via remote diagnostics.


The system configuration consists of a 19-inch rack-mountable control unit and a low profile laser head that can be mounted horizontally or vertically. The complete system can be either air-cooled for low output power performance or water-cooled for high output power performance. System operation is simple and various functions can be changed on-the-fly without powering down the system. As standard, the laser is available with either 10 or 40W output power emitting at 1,035nm. Other wavelengths, including green, are available upon request. www.nktphotonics.com


Fibre-coupled laser diode


Frankfurt Laser Company has launched the FBLD-980-10-FC- HHL, a fibre-coupled high-power laser diode. The 976nm diode delivers 10W output power from 200μm fibre and has a brilliant visible green aiming beam. Opposed to red, a green aiming beam is up to five times more visible to the human eye, meaning that in brightly lit environment such as operating rooms, the beam is clearly visible. Therefore it is suited for use in medical applications. The diode comes in a hermetically sealed HHL package and has an integrated thermal- electric cooling to ensure reliable laser diode performance. The company has also introduced the FLC300, a laser diode system, which delivers from 2mW to 300W at the fibre output. Possible wavelengths are in the range of 450 to 1,550nm. The operation conditions such as power, current, temperature as well as pulse width and frequency are clearly visible on the LCD display and can be adjusted. As well as manual control, the system can be controlled by programming it via an RS232 port. www.frlaserco.com


34 ELECTRO OPTICS l MARCH 2014


Coherent has launched its Fidelity laser, a sealed- box fibre laser that delivers short (<70fs) pulse widths and high (>2W) average power at 1,055nm. The laser is an economical oscillator that is air-cooled with a footprint of 318 x 318mm, and produces a high quality (M2


<1.2) output beam. This


makes it suitable for applications in multiphoton imaging, terahertz generation, and material research. Fidelity’s high repetition rate (64MHz) enables fast data acquisition. It also includes an integrated and electronically adjustable pre-chirp adjustment to fine-tune or minimise the pulse width at the experiment itself. Fidelity is suitable for most scientific applications


MFP fibre lasers


Vonjan Technology, a German-based provider of laser sources, F-theta optics and deflection units, has introduced its L Series of MFP fibre lasers. The MFP-5L, MFP-10L, MFP-15L and MFP-30L models are compact, air-cooled fibre lasers with output power of 5, 10, 15 and 30W respectively.


OEM monolithic light engine


Melles Griot has introduced the OEM Monolithic Light Engine. The light engine can shake, rattle, and ship without needing to be realigned. It is available in three or more output wavelengths from 405 to 785nm and powers up to 200mW. The hermetically sealed design, combined with a patented beam-combiner results in rock-solid stability when subjected to mechanical shock, vibration and temperature changes. The internal laser components, combining elements, and


WhiteLase supercontinuum laser


Fianium has introduced the WhiteLase SC480- 20, a high brightness supercontinuum laser with 20W of total power. This system has over 3W of visible (350- 750nm) and 4.5W of extended visible (350-850nm) power and a continuous output


UV nanosecond lasers


Photonics Industries has released a UV nanosecond laser (the DSH-355-25), delivering up to 30W of intracavity harmonic average power at 355nm from a compact, rugged, monolithic laser head. Photonics Industries’ patented intracavity UV generation is based on non-consumable THG crystals with no crystal indexing required. It allows for a simpler optical resonator for better stability, insensitive to ambient temperature changes.


such as ultrafast spectroscopy and supercontinuum generation. Compared to titanium:sapphire-based systems, Fidelity’s combination of very short pulses with high power at long wavelengths is a particular advantage in deep in-vivo bio-imaging applications such as optogenetics. www.coherent.com


Depending on the model, they are designed for applications with pulse frequencies between 10 and 45kHz and are suited to integration in laser marking systems. In addition, the new models all include an integrated aiming beam and are equipped with a central wavelength of 1,064nm. www.vonjan-tech.de


beam shaping optics are held at a constant temperature in a compact package, which delivers


good pointing stability, low optical noise and power stability. Customised beam profiles, focal distances and modulation parameters are available per OEM requirements. www.mellesgriot.com


spectrum from 480nm to 2,400nm. The laser produces picosecond pulses at 80MHz repetition rate, which can be varied down to 100kHz with the pulse picker option, enabling application possibilities in both steady state and lifetime measurements. www.fianium.com


The more efficient harmonic conversions enables lighter weight/smaller form factor laser heads


that can be mounted on movable platforms. The higher power intracavity UV nanosecond lasers are suitable for micromachining applications such as flexible PCB cutting and wafer scribing. www.photonix.com
