The WN400 Series is a high performance lamp pumped Nd:YAG laser designed to deliver high pulse energy, high repetition rate operation, and excellent beam quality in a compact and reliable platform. Its innovative optical configuration integrates both the master oscillator and amplifier active elements into a single pump chamber powered by one flash lamp, providing an efficient and cost effective laser architecture.
Based on a proven ring cavity design, the WN400 achieves excellent beam quality, while the single pass amplifier incorporates optical compensation techniques to minimize thermo optical effects and maintain stable output performance. The optimized optical design produces a nearly perfect flat top beam profile, ensuring uniform energy distribution across the beam area for demanding applications requiring precise laser interaction.
The WN400 provides an output wavelength of 1064 nm with pulse energy up to 200 mJ and pulse width of less than 5 ns. With a beam diameter of 12 mm, the system delivers consistent high quality laser pulses suitable for a wide range of scientific and industrial applications.
Designed for reliable long term operation, the WN400 features a vibration and dust resistant housing, a single flash lamp configuration with a lifetime exceeding 100 million pulses, and a simplified replacement procedure without requiring access to the laser head optical cavity. These features reduce maintenance requirements while ensuring stable operation in demanding environments.
HARMONIC GENERATORS
The WN400 laser is supplied with built in SHG, THG, and FHG in its standard configuration. Upon request, these harmonic generators can also be provided as external stand alone modules. FiHG is available only as an external unit.
OPO
Upon request, the WN400 laser can be upgraded with an optical parametric oscillator from the WN 400 series. This configuration provides a source of continuously tunable laser radiation across a broad spectral range from UV to IR.
ATTENUATOR
The laser can be equipped with a PC controlled attenuator. Available options include a unit optimized for operation at a specific wavelength or an achromatic attenuator designed to simultaneously attenuate all laser harmonics from 266 nm to 1064 nm.
