High-power, high repetition-rate, green-pumped, picosecond LBO optical parametric oscillator

Abstract

We report on a picosecond, green-pumped, lithium triborate optical parametric oscillator with record-high output power. It was synchronously pumped by a frequency-doubled (530 nm), pulse-compressed (4.4 ps), high-repetition-rate (230 MHz), fiber-amplified gain-switched laser diode. For a pump power of 17 W, a maximum signal and idler power of 3.7 W and 1.8 W was obtained from the optical parametric oscillator. A signal pulse duration of ~3.2 ps was measured and wide tunability from 651 nm to 1040 nm for the signal and from 1081 nm to 2851 nm for the idler was achieved.

Characteristics of optical parametric oscillators synchronously pumped by second harmonic of femtosecond Yb:KGW laser

“…Due to limited laser wavelength tuning capabilities, optical parametric amplifiers (OPAs) [1][2][3][4] and synchronously pumped optical parametric oscillators [5][6][7][8][9][10][11][12][13][14] are used as sources of tunable ultrashort coherent radiation. To generate tunable radiation with high repetition rate, low pulse energy mode-locked pump lasers, synchronously pumped optical parametric oscillators are used.…”

Generation of mode-locked optical pulses at 1035 nm from a fiber Bragg grating stabilized semiconductor laser diode

“…frequency-doubling, the pumping of parametric oscillators and supercontinuum generation [1][2][3]). Semiconductor Laser Diode (SLD) seeded, fiber MOPA sources represent highly attractive sources for such applications, combining the compactness, stability and cost-effectiveness associated with semiconductor devices with the ready power-scaling possible using fiber amplifiers.…”

Generation of 167 W infrared and 124 W green power from a 13-GHz, 1-ps rod fiber amplifier

“…High-average power, high repetition rate infrared (IR) and green picosecond (ps) pulses are important sources for laser machining [1], optical parametric oscillators [2], and future particle accelerators [3]. Fiber lasers are an excellent choice as they can deliver high average power with high slope efficiency and diffraction-limited beam quality [4,5].…”
