TOPTICA presents “All Wavelengths” at CLEO

May 4, 2018

From May 15th – 17th, TOPTICA Photonics will present their high-performance lasers at CLEO Conference at San Jose Convention Center, San Jose, California (USA). At booth 1825, TOPTICA will showcase their broad product portfolio which covers All Wavelengths from deep-UV (190 nm) to terahertz radiation (0.1 THz, corresponding to 3 mm). These lasers support a multitude of applications in quantum technology, microscopy and materials metrology.

In particular, TOPTICA’s tunable diode lasers are ideal tools for demanding tasks in modern quantum optics experiments. They are available with stabilized wavelengths and narrow linewidth, ultrawide mode-hop-free tuning ranges and intelligent control features. With the help of frequency-conversion and amplifier systems, these lasers cover an ultrabroad spectrum reaching from 190 to 3500 nm with high output power up to 4W.

The DFC CORE + is TOPTICA’s compact high-performance frequency comb. It features turnkey operation in a robust, small volume housing while supporting high-end applications like optical clocks or low-noise microwave generation. High bandwidth locking to an optical reference is available remotely through a convenient user interface and will be demonstrated LIVE at the CLEO and IFCS exhibitions.

For applications like high-resolution spectroscopy and interferometry the DFC product line can be combined with TOPTICA´s diode lasers and locking electronics to offer complete stabilized diode laser systems between 420 and 2200 nm. Characteristics like remote locking of TOPTICA diode lasers to the comb or integration into ready to use, transportable 19-inch rack systems (DFC SDL) help simplifying customers everyday life.

With the new MDL pro, TOPTICA’s established product line of tunable diode lasers are now available in a transportable and compact design. It combines four tunable diode lasers in one 19-inch module with the same specifications as TOPTICA’s well known DL pro and DFB pro series. The digital low-noise DLC pro controller is at the heart of the newest platform of these tunable diode lasers. The MDL pro combines excellent laser performance with the unique and easy to use standard electronic sub-racks. Such a transportable solution will advance the development of mobile experiments like optical clocks, quantum computers or sensors.

Mode-hop-free tuning lasers are an important requirement for more and more applications like micro-cavities, quantum dots and component testing. A new generation of external cavity diode lasers (ECDLs) called CTL (continuously tunable laser) is ideally suited for this task. These lasers offer very wide tuning with exceptional resolution while at the same time showing narrow linewidth, lowest noise and drift. The CTL enables quantum technology experiments that were previously not possible with ECDLs. Partly, these improved properties stem from the all-digital controller, DLC pro. It offers the lowest commercially available noise figures for diode current, piezo voltages and temperature, resulting in free-running linewidths below 10 kHz. DLC pro also has integrated frequency and power stabilization functionality and is conveniently controlled via an integrated touch/knob interface – or remotely via TCP/IP. It is also responsible for guaranteeing single mode-operation in an active feedback loop (SMILE) and for automatically optimizing the laser cavity (FLOW) if necessary to insure hands-off operation.

TOPTICA’s frequency-converted diode lasers provide deep-UV wavelengths as short as 190 nm. By providing essential wavelengths like 193 nm, 213 nm, 257 nm or 405 nm in pure cw-TEM00-mode quality, the DLC TA-SHG/FHG pro is an ideal solution for testing and inspection or advanced material processing, e.g. lithography patterning. White-light holography is served with our tunable solutions around 457 nm, 532 nm and 647 nm. The lasers provide more than enough power for each application. On top of that, they are much easier to handle at considerably lower operating costs.

The multi-laser engine iChrome CLE for biophotonics provides 405, 488, 561 and 640 nm with 20 mW at the end of the fiber. The iChrome CLE is a cost-effective system for multi-color microscopy applications due to its compact design and economic operation. Even the 561 nm light is generated by a laser diode instead of a solid-state laser, allowing this system to be directly modulated at high speed (1 MHz) while maintaining complete-off, i.e. zero photons, in the dark state. The iChrome CLE is the latest member of TOPTICA’s iChrome product line which also includes the powerful iChrome MLE (up to 100 mW and four laser lines). All iChrome systems have a unified user interface, unique modulation features and COOLAC, TOPTICA’s proprietary and fully automated beam alignment algorithm guaranteeing consistent power out of the fiber.

For multiphoton microscopy, TOPTICA’s FemtoFiber ultra femtosecond fiber lasers are excellent tools. These ultrafast lasers provide powerful pulses centered at 780 nm (500 mW average power and below 150 fs pulse duration), at 1050 nm (5 W average power with an unprecedented short pulse duration of typically 90-100 fs), as well as 1560 nm (up to 2 W power and 200 fs pulse duration). They are ideal light sources for multiphoton (SHG) microscopy, supercontinuum generation, material processing, as well as OPCPA or amplifier seeding.

Semicon inspection or Raman applications at 266 nm are enabled by TOPTICA’s TopWave 266. This industrial-grade, continuous-wave laser system provides 300 mW. It stands out with excellent power stability, low noise and extended lifetime with a digital control architecture and an optimized, completely sealed doubling cavity.

Contact-free material characterization with unprecedented data rates is now possible thanks to TOPTICA’s TeraSpeed. This superfast terahertz-sensing platform enables applications like non-destructive testing, plastic inspection or process control with a sampling rate of 100 million data points per second. The TeraSpeed complements TOPTICA’s unique portfolio of terahertz systems, which also includes TeraFlash, a time-domain terahertz platform. TeraFlash has an unsurpassed peak dynamic range of 90 dB and a bandwidth of 6 THz. If a frequency-domain terahertz platform is required, TOPTICA’s TeraScan allows for a frequency resolution better than 10 MHz and a dynamic range up to 100 dB.

TOPTICA’s Faraday Optical Isolators are specially designed and manufactured in-house by the laser experts of TOPTICA to give industry-leading performance in single and dual stage configurations. Single stage devices provide at least 38 dB isolation and 85 % transmission (>43 dB and >92 % average) over individual wavelength ranges in total spanning 395 - 425 nm and 630 - 1400 nm. Dual stage models provide at least 60 dB isolation and 80 % transmission (> 67 dB and >90 % average) over individual wavelength ranges in total spanning 640 - 1100 nm. All models are wavelength adjustable and can handle power densities up to 4 kW / cm2.
