Center wavelengths , , nm The master laser beam is coupled into the small single-mode channel at the AR coated rear facet of the tapered amplifi er chip. The single-mode channel acts as a spatial mode fi lter like a single-mode fi ber. The close-fi tting tapered angle is adapted to the diffraction angle of a single-mode laser at a specifi ed wavelength.
The DLX laser consists of an external cavity diode laser with a specifi cally designed high power laser diode. For the versed scientist it allows easy integration into an existing setup. The BoosTA features compact electronics that are integrated into the laser head. High Power Diode Lasers and Amplifi ers In the past, powerful tunable cw light could only be attained by employing large solidstate lasers or dye ring laser systems with expensive pump sources. In TOPTICA developed the fi rst tapered amplifi er TA system, a semiconductor laser solution offering full tunability with the lowest operating costs and long lifetime.
Overcoming power limits of laser diodes The output power of single-mode laser diodes is limited and not suffi cient for a variety of applications. With tapered amplifi er based laser systems, TOPTICA has managed to overcome both limitations, offering not only high power and 16 www.
The laser beam is amplifi ed in a single pass through the tapered region, without losing its high spectral and spatial quality, and leaves the chip through the AR coated large output facet. This MOPA concept combines the tunability and linewidth of the master oscillator with the high power and excellent beam quality available from tapered amplifi ers.
The modular and open concept of these laser systems make them versatile and fl exible. The TA pro is a member of the pro series and consistently follows its concept: maximum stability and ease of use. Together, the TA systems offer the broadest wavelength coverage and highest output powers. It offers tunable output in a single spatial mode and narrow linewidth. Various options are available, ideally suited for spectroscopy and related applications.
The BoosTA amplifi er system employs the tapered amplifi er chips of the TA in a low cost and compact amplifi er module. Therefore the TA pro features the DL pro as master laser see pages 9 - The other components have to ensure not only stable beam pointing, but also the best possible optical and thermal performance.
The TA pro utilizes completely new mirror mounts based on fl exure technology, that are conveniently adjustable from the top patent pending. They ensure easy coupling into the tapered amplifi er, while offering superior stability to prevent intensity fl uctuations that might arise from beam pointing variations. The unit containing the TA chip and optics is optimized to be most stable and to offer best heat conductivity.
For beam shaping, TOPTICA uses custom made optical components, achieving the best possible beam profi le and fi ber coupling effi ciency. Compact integration with high quality components A high quality optical isolator placed between the master and the amplifi er not only protects the master laser, but also guarantees spectrally robust operation. Between isolator and tapered amplifi er a probe beam is split off and is available for spectral stabilization and monitoring purposes.
All mechanical and optical components are integrated in a housing, that is machined from a solid block. The TA pro is easy to align, very stable when aligned, and it offers the best possible beam quality available from tapered amplifi ers. The TA pro is well-characterized, and available in three st and ard wavelengths. With seed the incoherent background is suppressed by approx.
DFB based diode lasers are described on page Their mode-hop free tuning range up to GHz is by far greater than that of external cavity laser systems. The linewidth of DFB lasers is approximately 0. These systems deliver up to mW around nm, and up to mW around nm. The TA can be tuned to the Lithium atomic resonance at nm and to the Argon ion resonance at nm.
Eliminating the need for big and expensive dye lasers, this is the ideal system for Lithium laser cooling and for plasma spectroscopy. P I characteristics of three typical tapered amplifi ers.
The TA is a cost effective way to achieve single frequency laser radiation in the Watt regime. TA in red. It provides up to 1 W output power in a single spatial mode with very narrow linewidth. Its high wavelength stability and superior life time make it ideal for dem and ing applications such as highresolution spectroscopy.
TOPTICA's proprietary thermal management and robust mechanical design ensures longterm stability and reliable operation. RockSolid greatly reduces the laser's sensitivity to vibrations and acoustic noise.
The laser is therefore easy to stabilize without compromising the mode-hop free tuning range. The DLX provides the space for integration of a 60 dB isolator into the laser head.
Modulation and stabilization options The DLX-Mod option permits fast modulation and control of the laser frequency. Together with the built-in Piezo actuator it can be used to tightly lock the laser to atomic transitions or high-fi nesse cavities to further reduce the laser linewidth. The laser system is complemented by a modular set of control electronics from the established DC series.
A detailed description of available control modules can be found in the Electronics and Photonicals sections see pages 30 - It includes computer controlled st and -alone electronics and all the optics to accept a collimated laser beam as input and to provide a wellcollimated output beam. The user is responsible for optical isolation of the seed laser, and for appropriate mode matching to the tapered amplifi er. The amplifi er chips are the same as in the TA system, yet the electronics are integrated into the laser head, resulting in a very compact amplifi er system.
The system features not only a driver current Typical saturation behavior of tapered amplifi er chips for various amplifi er currents more than 40 mW seed power is not recommended. The separate power supply minimizes the impact of thermal and electronic radiation EMC on the laser head. The integration of an optional output isolator into the laser head reduces unwanted back refl ections into the amplifi er. Optional single-mode fi ber coupling is available for fi ber input and fi ber output.
When both are equipped FiFo option , the amplifi er is particularly easy to setup. Short-link Link Embed. Share from cover. Share from page:.
