Ultrafast Fiber LasersErbium-doped fibers are making it possible to develop compact, diode-pumped sources of ultrashort pulses for a variety of applications. Operating principles of these devices are reviewed and recent experimental progress in our laboratory on soliton and stretched-pulse lasers is described.作者: Ostrich 時(shí)間: 2025-3-24 12:35
Time-Domain Jitter Measurement of Modelocked Fiber LasersThe timing jitter of modelocked Er:doped fiber lasers is measured using a new time-domain method involving cross-correlation.

Generation of 100 TW, Sub-20 fs Pulses at a 10 Hz Repetition Rate in Ti:SapphireWe have developed a compact three-stage Ti:sapphire amplifier laser system that produces a peak power in excess of 100 TW for a pulse duration of less than 19 fs and an average power of 19 W at 10 Hz repetition rate. The spatial beam quality is about twice the diffraction limited for the full amplified, compressed output pulse.作者: LAST 時(shí)間: 2025-3-24 19:29 作者: GLOSS 時(shí)間: 2025-3-25 00:14 作者: 惰性氣體 時(shí)間: 2025-3-25 04:27

Broadband Operation of a Ti:Sapphire Laser Using Novel Double-Chirped Mirrors and Semiconductor Satuor (SESAM) that leads to reliable self-starting operation. With a single set of novel ultra-broadband DCMs we can tune the center wavelength of self-starting 30-fs pulses over 300 nm. The exchange of the cavity mirrors, which is usually neccessary when tuning over such a broad wavelength range, can 作者: Bravura 時(shí)間: 2025-3-25 15:53
