RADIANT 355

The RADIANT tunable laser series utilizes optical parametric oscillator technology to generate wavelengths over a broad range in the UV, VIS and IR. Integration of system components into one compact unit increases ruggedness, minimizes misalignment and allows the user to reposition the system. Included verification hardware enables the user to confirm beam paths are preserved after shipment or relocation. Hermetically sealed modules protect sensitive optical materials from the environment. All tunable beams exit the system from the same port resulting in one beam path to the end-user’s application. Wavelength tuning is motorized and computer controlled.

Option 1 Group

Energy Level

The RADIANT can be configured for two energy levels, as presented in the tuning graphs. Select the desired configuration based on the graph. The outside dimensions are identical.

Option 3 Group

Wavelength Tunable UV Modules

The tuning range of the OPO can be extended into the UV by doubling the OPO Signal or mixing it with the pump laser. The UV/EUV option consists of a single, hermetically-sealed module that is removeable for full power access to the OPO energy and can be replaced with no need for realignment. The UV beam is separated from other wavelengths in the beams path (pump, harmonics, and OPO) by optics that are mounted on a computer controlled motorized stage. The position of these optics changes automatically depending on the desired output wavelength. All tunable beams, OPO and UV, exit the system from the same location resulting in one beam path to the end-user’s application.

Option 4 Group

Fourth or Fifth Harmonic Generator Extension

Fourth (266 nm) or fifth (213 nm) harmonic generators can be attached to the system through an external housing that adds 5.2 in (12.7 cm) to the width of the system.

Option 5 Group

Motorized Variable Attenuator

Vary the OPO pulse energy by choosing the Motorized Variable Attenuator (MVA) option. By default the end-user changes the OPO pulse energy by changing the pump laser pulse energy through software command. However, OPO pulse-pulse energy instability increases at lower pump laser energy levels. The MVA option involves maintaining the pump laser pulse energy at maximum and using optical attenuation to change the OPO pulse energy without compromising pulse energy stability. The MVA option connects through the electronics unit for computer control. Systems with UV tuning options require removal of the UV module to install the end-user insertable MVA option and vice versa. The MVA option can also be removed for full OPO pulse energy access and reinstalled without need for alignment.
