Femtosecond Laser Cavity Dispersion Measurement Using Soliton Propertiesa classical CPM laser using rhodamine 6G and DODCI dyes. All the mirrors were single stack coated for 100% reflectivity at normal incidence at 620 nm. With freshly prepared dyes, pulses as short as 31 fs (assuming a sech. profile) are obtained.

Hybrid and Passive Mode Locking in Coupled-Cavity Lasers low-gain He-Ne lasers involved there was an obvious practical advantage in minimising insertion loss by siting the relevant modulator in the external cavity. The alternative concept of exploiting an optical nonlinearity in an external coupled cavity was first described by Mollenauer and co-workers

Ultrashort Pulse Generation with Additive Pulse Modelocking in Solid State Lasers: Ti:Al2O3, Diode Ptechnique uses a laser coupled with a nonlinear external cavity to produce modelocking by a fast saturable absorber like mechanism without the need for active modulation. Ultrashort pulse generation is demonstrated in Ti:Al.O., diode pumped Nd:YAG and Nd:YLF.

Chirp in Actively Modelocked Diode Lasersdispersion . In this paper, we present time-resolved chirp measurements of a modelocked external-cavity InGaAsP laser. These measurements reveal a wide range of chirp values for different laser operating conditions. A self-consistent modelocking theory which incorporates both carrier-induced in

Femtosecond Color Center Lasers near 2.8 ,m with HgCdTe Multiple Quantum Well Saturable Absorbernerates pulses as short as 120 fs and the RbC1:Li CCL generates pulses as short as 190 fs, which are the shortest pulses in the mid-infrared wavelength range. These CCL are the only direct laser source of sub-picosecond pulses in this wavelength range. Our results extend the semiconductor passive mo

Dramatic Reduction of the Amplitude Noise of Colliding-Pulse-Modelocking Dye Lasersenerating stable optical pulses of less than 100 fsec duration. The probably most important improvement of the CPM laser has been the addition of a four-prism sequence to adjust the intracavity group velocity dispersion . Although the CPM laser has been object of extensive studies to understand t

Femtosecond Laser Cavity Dispersion Measurement Using Soliton Propertiesser..We present in this paper two experimental measurements of the intracavity dispersion of a colliding pulse mode-locked (CPM) dye laser. This parameter is of crucial importance for this kind of laser and, until now, has never been experimentally measured. First, we will show that using soliton pr
