Parametric Nonlinear Mirror in Actively Mode-Locked Nd:YAG Laser with Negative Feedback Controld as a mode- locker both for pulsed. and cw lasers.. A stable NLM operation providing the reliable formation or shortening of light pulses takes place at the sufficiently high intensity of radiation in laser cavity which can be attained due to the use of additional active mode-locking.

Tunable UV Picosecond Pulse Generation Using Fast Spectral Evolution of Low-Q Short Dye Laser Oscill crystals and noble gases, third-harmonic generation in noble gases and anti-stock Raman shifting.. The existing commercially available UV ultrashort pulsed laser systems are mainly based on non-linear frequency converting of tunable visible or near infrared laser systems that are complicated and expensive up to now.

All-Solid-State Tunable Diode-Pumped Ultrafast Laser Oscillators and Amplifiers for Real-World Appliystems which may be commercialised and applied in a wide range of scientific and technological areas. Self-starting KLM has recently been shown to be straightforward in Ti: sapphire lasers and may be extended to any other solid-state laser medium to yield a relatively simple picosecond or femtos

Powerful Ultrashort Pulse Generation in Ti:Sapphire based on the concept of chirped pulse amplification (CPA). have been devised. Recent advances in the CPA technique resulted in amplification of optical pulses of ≈ 30 fs beyond the TW level at a repetition rate of 10 Hz.. Amplifier systems with kHz repetition rates produce femtosecond pulses with e

Mode-Locking of Solid State Lasers by Cascaded Second Order Nonlinearitieslasers exploiting fast nonlinearities. For Nd:YAG and Nd:YLF the most successful techniques up to now have been Additive Pulse ML., Kerr Lens ML. and Antiresonant Fabry-Perot Saturable Absorber ML based on absorption saturation in semiconductors. Pulses with duration below 10 ps have been obtained f
