Toptica DLC TA-SHG pro - Intelligent features and touch control

toptica DLC SHG pro

The digital DLC TA-SHG pro offers unprecedented convenience and best specifications for challenging experiments with frequency-converted tunable diode lasers.  

New conveniences for working with frequency-converted diode lasers!

TOPTICA’s latest DLC TA-SHG pro systems offer the lowest noise levels, narrowest linewidths and a simpler way to manage laser operation. Thanks to new, automated functions these systems revolutionize the daily work with frequency-converted lasers.

Intelligent, automated alignment features integrated directly into the laser head transform the work with lasers: With the push of a button, the AutoAlign option re-optimizes the SHG system output power by maximizing the coupling efficiency of the laser into the TA chip and the SHG resonator via built-in intelligence and servo-controlled flexure mirror mounts. The PowerLock option automatically compensates residual drifts caused by changing environmental conditions, offering unvarying stable laser output with constant power. Fiber-coupled systems using the FiberMon option can monitor the optical power coupled to the SHG output fiber. In combination with the FiberMon option, AutoAlign and PowerLock are also available for fiber-coupled systems.

Standard models are available at 405, 425 nm, and 633 nm; other wavelengths between 370 and 640 nm can be provided on request. The laser features various modulation inputs and includes an isolator. Fiber coupled versions are optionally available.

Toptica Laser Diodes

 Specify your wavelength – Toptica can provide it.

TOPTICA offers a large variety of wavelength-selected single-mode laser diodes from stock. Among more standard laser diodes, you will find "pearls" such as 397 nm, 715 nm or 1120 nm right from our stocklist, wavelengths for which we are probably the only supplier in the world.

TOPTICA can integrate any diode from the stock lists into a tunable diode laser system, however, you can also purchase the diode separately. Each type of diode is carefully tested in an external cavity laser configuration with respect to coarse tuning range, mode-hop-free tuning range and power limits. The results are disclosed on request to the customer in a detailed datasheet.

In case you can still not match your wavelength of choice, call us – and chances are very high that we can provide it within very short time.

Nice price diodes are either diodes, that have been superseded by better diodes or that do not run nicely in ECDL setups. Nice price diodes will not be integrated into ECDLs by TOPTICA.

In these downloads you will find wavelengths, output powers and part numbers on our regularly updated stock lists. Give us a call and we will make a reservation for the particular diode of choice for you.
