Electronically tuned picosecond Ti:sapphire laser
A widely electronically tunable picosecond Ti:sapphire laser is demonstrated without any mechanical rotation or movement for the first time. With the second harmonics of the Nd:YAG laser as a pump source, the laser produces 10 ps pulses with a maximum output power of 350 mW. The wavelength of the self-starting ultrashort laser pulses can be rapidly and arbitrarily accessed in the region from 76...
متن کاملTilt-tuned etalon locking for tunable laser stabilization.
Locking to a fringe of a tilt-tuned etalon provides a simple, inexpensive method for stabilizing tunable lasers. Here, we describe the use of such a system to stabilize an external-cavity quantum cascade laser; the locked laser has an Allan deviation of approximately 1 MHz over a one-second integration period, and has a single-scan tuning range of approximately 0.4 cm(-1). The system is robust...
متن کاملN ov 2 00 5 Dispersion managed mode - locking dynamics in a Ti : Sapphire laser
We present what is to our knowledge the most complete 1-D numerical analysis of the evolution and the propagation dynamics of an ultrashort laser pulse in a Ti:Sapphire laser oscillator. This study confirms the dispersion managed model of mode-locking, and emphasizes the role of the Kerr nonlinearity in generating mode-locked spectra with a smooth and well− behaved spectral phase. A very good a...
متن کامل2PE-STED Microscopy with a Single Ti: Sapphire Laser for Reduced Illumination
We reported a new effective approach to carry out two-photon excitation stimulated emission depletion (2PE-STED) microscopy using a single Ti:sapphire laser system. With an acoustic-optic Bragg cell, the modulated-CW 2PE STED microscope had the benefits of both CW and pulse approaches: lower input power, simple optical scheme and no complicated synchronization. Additionally, it also took advant...
متن کاملTwo-photon absorption cross section of excited phthalocyanines by a femtosecond Ti-sapphire laser.
In the past few years, photodynamic therapy (PDT) has become a major treatment for neovascular age-related macular degeneration (AMD) in which there is abnormal growth of choroidal neovasculature (CNV) that eventually obscures central vision, leading to blindness. However, one of the main limitations of current PDT is the relatively low specificity of the photosensitizer (PS) and light for path...
