We derive analytic expressions for the Brillouin thresholds of square pulses in optical fibers. The equations are valid for pulse durations in the transient Brillouin scattering regime (less than 100 nsec), as well for longer pulses, and have been co

We report on pulsed fiber lasers with up to 1MW peak power, 1mJ pulse energy in 10ps to 10ns pulse duration, employing standard large core Yb-doped fiber. Visible and near UV pulsed emission with highest frequency conversion efficiencies will be repo

We report on a pulsed laser source whose wavelength can be switched between 585 nm, 600 nm, and 616 nm. The pulses are approximately 1 nsec long, the repetition rate is 20 MHz, and the pulse energies are 25 to 50 nJ. The laser source uses a laser dio

We demonstrate 30 W of average UV power, at 353 nm, by harmonically converting the output of a seeded cascade of fiber amplifiers operating at 1060 nm. The UV output represents 46% harmonic conversion efficiency from the fundamental beam. The all-fib

We demonstrate an all-fiber-amplifier, MOPA architecture supporting variable pulse repetition frequencies and pulse widths. The system operates at near infrared wavelengths of ∼1064 nm and supports pulse repetition frequencies up to 2 MHz and pulse

We describe a passively mode-locked, diode-pumped Nd:YAG laser that is used for frequency-conversion applications. The laser is based on a Direct-coupled Pump gain element and saturable Bragg reflector. The laser produces a 20-ps pulse with a 100-MHz

The trend in micro-machining lasers is toward greater average power and higher repetition rate, in order to increase throughput, with pulse energy and peak power held roughly constant, as determined by the small scale of the feature. At repetition ra

A cladding-pumped Nd:silica fiber with a fundamental-mode cut-off near 1000 nm was used to build an amplifier with gain over a range near 920 nm. Pulses from an Nd:YVO4 passively Q-switched laser were amplified and then frequency doubled in LBO to pr
