Litron Tunable Wavelength Lasers
The Aurora II Integra series combines a Type II BBO broadband OPO and Nd:YAG nanosecond pump source into a single laser head, using an ultra-rigid Invar optical rail to provide class-leading performance and stability. True no-gap tunable output from 410 to 2600nm with options to extend into the 210 to 410nm UV range as well as direct access to the pump laser and its harmonics make the Aurora II the perfect choice for a wide range of research and industrial applications.
AURORA II INTEGRA
Integrated Nd:YAG Pumped Type II BBO OPO
The Aurora II Integra series combines a Type II BBO broadband OPO and Nd:YAG nanosecond pump source into a single laser head, using an ultra-rigid Invar optical rail to provide class-leading performance and stability. True no-gap tunable output from 410 to 2600nm with options to extend into the 210 to 410nm UV range as well as direct access to the pump laser and its harmonics make the Aurora II the perfect choice for a wide range of research and industrial applications.
The integrated fully-motorised design eliminates the need for user alignment and adjustment even when relocating the laser head. With a choice of pump sources from Litron’s wide range of Nd:YAG lasers, a highly modular layout and even bespoke component optimisation, tailoring the Aurora II into a flexible, customised solution has never been easier.
AURORA 1.57 OPO
Fully Integrated 1.57µm OPO and 1064nm Pump Laser System
The Aurora-1.57 is a 1064nm pulsed Nd:YAG laser with a fixed wavelength OPO optimised for 1.57µm operation. The laser resonator and OPO are mounted on the same mechanical optical rail to ensure permanent alignment between the two components.
Active temperature control of the OPO crystal and pump laser ensures long term energy stability.
The laser head is sealed against environmental contamination to IP54 rating and is fully detachable at both the laser head and power supply. The exit port window can be easily replaced by the user if required.
Using the LPU series power supply, the laser power and control system and closed-circuit water to air cooling system are combined in a compact standalone unit. The system is controlled either via RS232 with the supplied software suite or using the LUCi touchscreen remote control. External triggering of the lasers is available via a TTL interface.
AURORA TRLi OPO
Pulsed Nd:YAG Laser and 532nm Pumped OPO
The Aurora II TRLi OPO combines a Type II BBO OPO resonator, a second harmonic generator and a variable attenuator into a single compact module that can be attached to any of Litron’s TRLi series of Nd:YAG lasers to provide tunable no-gap output in the 670 to 2600nm range. Incorporating design features used throughout Litron’s Aurora OPOs the TRLi module provides high stability, narrow linewidth and simultaneous signal and idler output in a self-contained unit that is interchangeable with the other harmonic units within the TRLi range. With little to no realignment required on reattachment, the TRLi OPO expands the output of these high energy compact lasers into the NIR range without losing the flexibility of accessing the Nd:YAG harmonics.
The Aurora TRLi OPO can be provided with a flashlamp or diode pumped source.
