Unique TIS-SF-777 laser has more narrow linewidth for Ti:Sa lasers on the present market. TIS-SF-777 laser has super-narrow linewidth (< 5 kHz/sec) and unique Auto Re-lock function which is extremely useful in a work with frequency stabilized laser.

General description
· Ring design, three wavelength selectors: birefringent filter, thin and thick etalons, electronically controlled thick etalon to ensure laser operation in a single longitudinalcavity mode.
· Ultra-narrow line width up to < 5 kHz rms (1 sec): active frequency stabilization to an external reference cavity, special fast PZT actuator with extended response bandwidth.
· Unique function Smart Auto-Relock that allows uninterrupted laser operation in the frequency stabilisation mode under arbitrary external perturbations.
· Actively thermostated high-finesse reference cavity, frequency drift <40MHz/hr.
· External lock capability for stabilization to an absolute reference (e.g. iodine saturated absorption line).

Wavelength range, power
· Laser optimized at factory for primary operation wavelength 780-800 nm
· Output power at 790nm+/-10nm 1.8W or better with 10W pump (DPSS, 532 nm, TEMoo).
· TEMoo mode, linear polarization.

General design
· Most of the mounts are placed on a horizontal base plate, which is also the top element of the compact rigid 3-D frame made from three invar rods that ensures high stability of the optical element positions.
· Ease of adjustment, simplified laser alignment in the ring configuration because of preliminary optimisation of the elements in the linear cavity, exceptionally accurate alignment of the pump beam position.
· Premium Ti:Sapphire crystal (FOM > 500).
· Enclosed cavity with nitrogen purge port.
· Ergonomical and reliable electronic control unit featuring a built-in generator for smooth scanning of the laser frequency.
