TItanium Sapphire Lasers
• In 1982 researchers at Lincoln Laboratory operated a tunable laser based on Ti:Al20 3 for the first time. A wide variety ofdevelopments in Ti:Alz0 3 1aser technology then followed the advances in crystal growth that occurred during the mid-1980s. Since that time researchers have demonstrated high efficiency, wide tunability, frequency-stable continuous-wave operation, and generation of very s...
متن کاملFluorescence of coumarins and xanthenes after two-photon absorption with a pulsed titanium-sapphire laser.
Fluorescence emission after two-photon absorption of coumarins and xanthenes in an alcoholic solution was measured in the tuning range of a femtosecond-pulsed titanium-sapphire laser (750-840 nm). Xanthenes, which have a low one-photon absorption in the near UV, show a higher fluorescence signal after two-photon absorption than the UV-excitable coumarins. When fluxes of 10(28) photons/(cm(2) s)...
متن کاملFemtosecond pulse generation from a titanium-doped sapphire laser using nonlinear external cavity feedback.
A continuous-wave, argon-ion-pumped, titanium-doped sapphire laser has been constructed. Pulses of 80-psec duration obtained through active mode locking have been compressed to less than 800 fsec using nonlinear external cavity feedback.
متن کاملFemtosecond Laser Ablation of Sapphire
INSTRUCTION Sapphire is widely used in the field of optical components and micromechanical devices owing to its useful mechanical, optical, and electrical properties. However, sapphire is mechanically and chemically difficult to machine because of its high hardness and chemical stability. The difficulty of machining sapphire has restricted the development of advanced device structures. As sapph...
متن کاملSpectral amplitude and phase noise characterization of titanium-sapphire lasers.
There are few methods capable of characterizing pulse-to-pulse noise in high repetition rate ultrafast lasers. Here we use a recently developed method, termed fidelity, to determine the spectral amplitude and phase noise that leads to lack of pulse repeatability and degrades the performance of laser sources. We present results for a titanium sapphire oscillator and a regenerative amplifier syst...
