The Constellation Series CW OPO carries forward the lineage, spirit and performance of the old Aculight Argos OPO but is it’s own new carefully crafted and updated product. It has lots of improvements and added features based on customer feedback. It is a robust “Turn Key” system that is easy to use, requires no user alignment and offers automated “hands free” mode-hop free tuning. It allows customers to remotely control and program tuning of the Etalon and PPLN crystal via stepper motor control for continuous mode-hop free tuning across wide wavelength regions. It also allows for simple manual push button driven tuning via a physical controller box with momentary stepper buttons or by a computer GUI Application. It is air cooled and runs on standard wall voltage.
It covers Mid-IR wavelengths from 1460nm to 4600nm and boasts “typical” maximum CW power levels of 4 watts in the A range, 3 watts in the B range, 2 watts in the C range and 1 watt in the D range. The Constellation uses a “modular” approach where the Mid-IR spectrum is divided and covered using four individually available modules. This approach has multiple benefits. First, it allows the design for each spectral region to be optimized for the best performing optical coatings and the best performing Etalon materials to maximize the power of each module while still retaining those famous ultra narrow idler linewidths of LESS than 1 Mhz. Secondly, it allows users more affordable solutions by purchasing only the coverage area they need, thus saving money.
It is available in both single frequency – narrow linewidth versions OR various Broadband configurations with broadband units delivering up to 10 watts of CW power! Both configurations are thus power and cost scalable depending on the pump level chosen. So you only pay for the wavelength region you need and the amount of power you need. This makes the Constellation CW OPO the most affordable, flexible, powerful narrow line width tool available! There are other places you can spend the money you save.
