Ultra-narrow-linewidth CW single-frequency
ring Ti:Sapphire laser,
model TIS-SF-777
TIS-SF-777 datasheet (1,9 Mb)
Flagship model
TIS-SF-777 of Tekhnoscan's CW single-frequency Ti:Sapphire
laser series features exceptionally narrow radiation
absolute line width that amounts
to only about
2-3 kHz rms (specification:
< 5 kHz rms). Frequency stabilisation of
the laser output is done with a thermostated high-finesse reference
interferometer and special PZT actuators that work in an extended frequency
range. The fast PZT-controlled mirrors allowed to avoid using an electro-optical
modulator in the frequency stabilisation system, which would otherwise
complicate the laser design and the electronic control boards as well as it
would be characterised by additional radiation losses. Because of the foregoing
laser TIS-SF-777 features relative simplicity and high reliability of design
as well as high output efficiency: maximum output power of this laser exceeds
1.5 W with a 10-W DPSS laser pump (532/515 nm).
Besides the uniquely narrow radiation line width, TIS-SF-777 also features a
unique function Smart Auto-Relock that
allows uninterrupted laser operation in the frequency stabilisation mode under
arbitrary external perturbations (acoustic, mechanic, etc.). Because of this
advanced Smart Auto-Relock function laser TIS-SF-777 offers the user a new
level of comfort when working with precisely stabilised single-frequency
Ti:Sapphire laser.
Applications: TIS-SF-777 is primarily
designed for high-precision experiments and technologies that make use of
cooled atoms and molecules, as well as for research in the new technologies
of high-density information recording (with resonant frequency doubler
FD-SF-07).
