Litron Lasers products are divided into several products groups:
Nano T Series – Ultra Compact Pulsed Nd:YAG Lasers
- Output Energies up to 310 mJ
- Stable telescopic resonator
- Electronically verified safety shutter
- 2nd, 3rd, 4th and 5th harmonics
- High energy TEMoo option available
Compact and rugged lasers with telescopic resonators giving low divergence beams with high spatial homogeneity. Energies available up to 290 mJ at 1064 nm and repetition rates up to 50 Hz. Harmonics available up to 266 nm. The Nano T inherits all of the features of the Nano L combined with the option of having a stable telescopic resonator. This resonator configuration produces a beam with a very low beam divergence.
This is a way of producing a low-divergence beam where the spatial beam profile does not exhibit localised very high peak powers such as those produced in the near field from Gaussian resonators. All this comes from a laser head with a footprint of 500mm x 96mm x 74mm.
LPY Series – High Energy Pulsed Nd:YAG Lasers
- Rugged invar stabilised construction
- Modular design
- Birefringence compensation
- Injection seeded option
- Line narrowing etalon option
- IGBT switching for long lamp life
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.
The modular design of the laser head allows a wide variety of resonator configurations to be offered, from single rod oscillators to fully birefringence compensating twin-rod-oscillator, twin-rod amplifier systems. Furthermore, a choice of stable, stable-telescopic or unstable Gaussian-coupled resonators is available, allowing the customer to specify a system that suits their requirements.
Aurora II Integra OPO – Tunable Pulsed Laser System
- Tuning range 410-710 nm and 710 nm to 2.3 µm
- UV harmonic option for 205-419 nm
- Linewidth <3 cm-1

- Motorised OPO tuning with optional closed loop wavelength feedback
- OPO optical compensation and 1064 nm variable optical attenuator
- 355 nm process shutter with energy monitoring as standard
- Full PC control via RS232
The Aurora II Integra range of type II BBO OPOs has been designed with reliability, stability and ease of use in mind. This allows researchers to concentrate on their experiments and industrial system integrators the peace of mind that their process will be consistent and robust. With a wide choice of integrated and optimised Nd:YAG pump lasers from 10 Hz to 200 Hz these are truly flexible systems.

TRLi Series – Compact High Energy Q-switched Pulsed Nd:YAG Lasers
- Plug and play interchangeable harmonic modules to 213 nm
- Intelligent motorised high speed auto-tuning of harmonics
- Auto-stabilisation for ‘set and forget’ operation
- Twin-rod architecture for high beam homogeneity
- Integrated motorised attenuator
- Easy connections and fast start up
- High energy and high repetition rate models
- Super Gaussian-coupled, stable and stable-telescopic resonator options
- Rugged industrial design
- LUCi touchscreen or PC control interface
The TRLi Series offers energies up to 850 mJ and repetition rates up to 200 Hz. They offer a fully birefringence compensated pulsed laser system offering both high energy and high repetition rate outputs. Its twin-rod architecture ensures high beam homogeneity even at very high average power outputs. The TRLi is designed to suit demanding industrial applications with a sealed laser head machined from solid aluminium, ultra stable mirror mounts and industry-leading lamp lifetimes. Resonator options include unstable Gaussian-coupled, stable, and stable-telescopic configurations, allowing for a multitude of applications.
Harmonic wavelengths are realised by bolt-on modules with auto-tuning capability that can be added or removed as required. Power supplies for the range include state-of-the-art IGBT switching into the flashlamp, giving increased efficiency and stability as well as significantly prolonging lamp life due to the much lower currents.
Intelligent laser head technology allows for easy head and power supply swapping as well as optional full auto-tracking of harmonic wavelengths. Auto-tracking continuously monitors the harmonic output energy and actively controls the phase-matching angle of the crystal to ensure that maximum conversion efficiency and therefore output is always achieved. This is most useful for the fourth and fifth harmonics where crystal absorption at the harmonic wavelength leads to self heating of the crystal.
