The taccor 1GHz laser offers frequency doubled light

03 Dec 2015

Laser Quantum is recognised as a leader in the production and development of Ti:Sapphire lasers with GHz repetition rates. Recently Laser Quantum cooperated with A·P·E Angewandte Physik und Electronic, Berlin. They have evaluated the performance of the taccor laser with the HarmoniXX SHG second harmonic generator to offer frequency doubled light at 1GHz.

Laser Quantum’s taccor range of ultrafast lasers has proven to be beneficial in applications such as multi-photon excitation microscopy, frequency comb generation and as part of pump-probe spectroscopy equipment due to their high repetition rate and high photon flux combined with low peak powers.

These applications however all rely on using the fundamental emission wavelengths of the Ti:Sapphire crystal centred around 800nm. Since the taccor has never been completely evaluated as a primary photon source for use with frequency doubling equipment, other applications such as picosecond ultrasound and time-resolved photoemission spectroscopy that require high energy photons have been unable to benefit from the taccor’s capabilities. In the case of time-resolved photoemission spectroscopy, the high energy photons are needed to excite then ionise the sample. The high repetition rate would offer significantly higher resolution measurements and speed up measurements.

In collaboration with A·P·E Angewandte Physik und Electronic, Berlin the taccor power was evaluated as a primary source for use with the HarmoniXX SHG frequency doubling unit and was shown to deliver output powers up to 250mW.

The taccor has shown to have benefits in a number of applications due to its unique high repetition rate, but when combined with the HarmoniXX SHG, a second harmonic converter from A·P·E, the advantages of the GHz repetition rate can be successfully used in applications that require powerful mode-locked light at the SHG wavelengths of Ti:sapphire.
