Titanium-doped sapphire (Ti:Sapphire) is a solid state laser medium capable of wavelength tunable laser operation over the broad range of visible and near infrared (NIR) spectral band. With the properly chosen cavity Ti:Sapphire laser can deliver coherent radiation in the range of wavelengths from 690 nm to 1080 nm. The gain in Ti:Sapphire medium spreads over the range >200nm and therefore can support generation of ultrashort pulses of less than 10 fs using Kerr lens mode-locking (KLM). The pulse duration from these lasers is determined by critical interplay between intracavity self-phase modulation in and negative group delay dispersion.
Del Mar Photonics femtosecond Ti:Sapphire lasers are available with 100 fs, 50 fs and 20 fs pulse durations as pre-assembled kits, as well as one-box oscillators integrated with DPSS pump lasers Trestles Finesse, and also a stand alone Ti:Sapphire oscillator with any suitable pump laser.
Del Mar Photonics Ti:Sapphire CW lasers are available with linewidth in GHz range 40GHz - 20GHz - 2GHz (Del Mar Photonics model Trestles CW) down to < 10 kHz rms in a new ultra-narrow-linewidth super-frequency-stable TIS-SF-777 laser designed for atom cooling and high-precision spectroscopy.
