An optical parametric amplifier, abbreviated OPA, is a laser light source that emits light of variable wavelengths by an optical parametric amplification process.

LIGHT CONVERSION is the world leading manufacturer of tunable wavelength femtosecond laser sources as well as diode pumped solid state femtosecond lasers.

Serving North America, RPMC Lasers offers a single-box optical parametric amplifier that converts ultrafast pulses from Ytterbium-based lasers into broadly tunable pulses with wavelengths ranging from 210 nm to > 10 µm. With intuitive, user-friendly PC software, an integrated mini spectrometer enables automatic tuning from 315 to 2600 nm.

APE offers a wide range of ultrafast optical parametric oscillators (OPOs), which can be pumped with 1-μm lasers or with Ti:sapphire lasers. Wide wavelength regions in the near and mid-IR can be addressed, pulse durations in the picosecond or femtosecond region are available, and pulse repetition rates can be in the megahertz or gigahertz region.

2025年3月12日 · We operate the OPA with a single pump to amplify signals through degenerate four-wave mixing (FWM), exploiting the optical Kerr effect (Fig. 1a).The optical energy is redistributed by annihilating ...

2022年9月23日 · Thorlabs' Ytterbia Optical Parametric Amplifier (OPA) is a femtosecond laser ideal for life science applications, such as three-photon microscopy, that require deep imaging depths, high signal-to-noise ratios, and minimal phototoxicity.

2024年10月23日 · Abstract: We developed a high-energy picosecond mid-infrared laser based on ZnGeP 2 (ZGP) optical parametric generator (OPG)/optical parametric amplifier (OPA), operating at a pulse repetition frequency (PRF) of 1 kHz. The laser system was equipped with a 2.09 μm high-energy picosecond laser amplification system as the pump source.

2025年3月11日 · The amplified signal laser, which is filtered out by dichroic mirrors from the output of OPA 1 and OPA 2, is accompanied by a residual pump laser and an idler laser at 3 μ m during the OPA process. The signal laser power is determined by an energy meter (Ophir, PE9-ES-C) to distinguish the pulse signal components from the CW seed laser.

2025年3月14日 · A single longitudinal mode (SLM) 486.1 nm blue pulsed laser was investigated by adopting a single-frequency distributed feedback laser (DFB) injected optical parametric oscillator (OPO) and optical parametric amplifier (OPA) structure, pumped by a 355 nm ultraviolet SLM laser at pulse repetition rate of 200 Hz.
