LPY Series – Superior performance through superior design.
Rugged, Invar stabilised, pulsed Nd:YAG lasers with high energy and high performance for industrial and scientific applications.
The LPY series of pulsed lasers have been designed to suit almost any industrial or research application in which a high-energy or high-specification Nd:YAG laser is required. Based around a fully self supporting Invar rail the LPY series exhibit both exceptional mechanical and thermal stability. A ‘no-compromise’ design approach is evidenced in the build quality, a parameter that sets these lasers well apart from any of their competitors.
LPY600
Pulsed Nd:YAG Lasers with Energies up to 1000mJ at 1064nm, and Repetition Rates up to 30Hz
The LPY600 series of pulsed Nd:YAG lasers was designed to suit almost any industrial or research application requiring a high-energy or high-specification Nd:YAG laser. The LPY600 series is based around a fully self supporting Invar rail to give exceptional mechanical and thermal stability. A ‘no-compromise’ design approach is evident in the build quality, a parameter that sets these lasers well apart from any of their competitors.
The LPY600 models are single rod oscillators or oscillator-amplifiers. Telescopic resonators produce low-divergence output beams that are spatially smooth in the near field suiting them to a host of pump source applications.
LPY700
Pulsed Nd:YAG Lasers with Energies up to 2000mJ at 1064nm, and Repetition Rates up to 200Hz
The LPY700 series of pulsed Nd:YAG lasers was designed to suit almost any industrial or research application requiring a high-energy or high-specification Nd:YAG laser. The LPY700 series is based around a fully self supporting Invar rail to give exceptional mechanical and thermal stability. A ‘no-compromise’ design approach is evident in the build quality, a parameter that sets these lasers well apart from any of their competitors.
The LPY700 models feature a twin-rod-oscillator design with birefringence compensation leading to high beam homogeneity and conversion efficiencies. Available with either Stable Telescopic or super-Gaussian resonators. Telescopic resonators produce low-divergence output beams that are spatially smooth in the near field suiting them to a host of pump source applications. Super-Gaussian resonators produce very low-divergence, single transverse mode output beams.
LPY7000
Ultra-High Energy Pulsed Q-switched Nd:YAG Lasers with Energies up to 3.5J at 1064nm, and Repetition Rates up to 50Hz
The LPY7000 lasers offer extremely high Q-switched outputs at repetition rates of up to 50Hz. Based around our proven self-supporting invar frame their robust build quality suits them to both industrial and scientific applications.
The lasers are provided in an oscillator, pre-amplifier, main-amplifier arrangement. The oscillator may be configured as a stable-telescopic resonator offering a low order multimode output with a smooth spatial and temporal profile, or as a super-Gaussian coupled resonator offering a single transverse mode output with slightly higher peak powers.
Lamp change is performed in a matter of minutes with no need for any re-alignment at all. An IP54 sealed case ensures that the laser is protected against the ingress of dirt and moisture when used in industrial environments.
LPY LOW REPETITION RATE
10-20Hz Pulsed Nd:YAG Lasers with Choice of super-Gaussian, Stable and Telescopic Resonators
The LPY600 models are single rod oscillators or oscillator-amplifiers.
The LPY700 models feature a twin-rod oscillator design with birefringence compensation leading to high beam homogeneity and conversion efficiencies.
Telescopic resonators produce low-divergence output beams that are spatially smooth in the near field suiting them to a host of pump source applications.
Super-Gaussian resonators produce very low-divergence, single transverse mode output beams.
LPY MEDIUM REPETITION RATE
30-50Hz Pulsed Nd:YAG Lasers with Choice of super-Gaussian or Stable Resonators
High Energy laser systems with industry leading spatial homogeneity – ideally suited to applications such as Ti:Sa pumping, Dye laser pumping and deflashing.
The LPY700 models feature a twin-rod-oscillator design with birefringence compensation leading to high beam homogeneity and conversion efficiencies. For industrial applications that require high pulse energy at higher frequencies particularly at 532nm at the UV wavelengths these lasers offer superior long term stability and spatial homogeneity.
LPY HIGH REPETITION RATE
100-200Hz Pulsed Nd:YAG Lasers with Stable Resonators for Industry and Science
Highly uniform spatial profiles make these ideal systems for applications such as deflashing, Ti:Sa pumping, dye lasers, OPO pumping and deflashing.
Litron offers a range of high energy, high repetition rate pulsed Nd:YAG laser systems. These systems offer industry leading flashlamp lifetimes and extremely homogeneous spatial profiles.
All systems feature a birefringence compensating twin-rod oscillator and, where used, a twin-rod amplifier. This ensures that the highest beam homogeneity and efficiency is obtained.
LPY TEM00
High Energy, True TEM00 Laser Systems Giving Near Diffraction Limited Beam Divergence
High energy true TEM00 outputs are obtained by means of an intra-cavity aperture behind the telescope within a stable telescopic resonator. The output beams from such systems typically have divergences that are within 15% of the diffraction limit. These systems therefore have output beams that are super-Gaussian in both the near field and far field.
INJECTION SEEDED LASERS
LPY Series of Pulsed Nd:YAG Lasers – Superior Performance Through Superior Design
All lasers from the LPY series can be fitted with an injection seeder to provide true SLM operation.
The Single Longitudinal Mode (SLM) output is actively controlled by a piezo drive to the rear cavity mirror to ensure long term stability of the output.
The seeder itself is mounted within the laser head on the ultra-stable Invar frame and is optically decoupled by two Faraday isolators for optical stability.
A choice is offered of seeding either super-Gaussian coupled resonators or true TEM00 resonators depending upon the application.
With the highly modular Invar structure of the LPY series it is also possible to seed a twin-head laser system from one seeder yielding two mutually coherent pulses. Output energies of up to 10J and repetition rates of up to 200Hz are available.
