Sapphire Lasers

Sapphire lasers provide industry-leading beam quality, exceptional power stability, and low noise. With over 50,000 lasers sold, its proven reliability and low cost of ownership make Sapphire lasers the ideal solution for the most demanding applications.

Features of Sapphire lasers include:

  • Continuous wave (CW) lasers
  • OPSL - Optically Pumped Semiconductor Technology
  • 9 wavelengths from deep blue (458 nm) to orange (593 nm)
  • Up to 500 mW output power
  • Single-frequency and fiber-pigtailed models

Sapphire LP/LPX is a series of free space CW lasers with up to 500 mW output power. It is the ideal laser solution for a manifold of applications such as life sciences, environmental protection, electronics, and metrology.

Sapphire FP (Fiber-Pigtailed) lasers are true fiber-pigtailed lasers ranging from deep blue (458 nm) to orange (594 nm) for life sciences, metrology and inspection applications.

Sapphire SF NX (Single-Frequency) lasers are the right choice for applications that need narrow and ultra-narrow linewidth light like Raman spectroscopy, interferometry, holography, metrology and inspection. Fiber pigtailed (FP) versions are also available.

Sapphire CDRH Controller provides both controller and power supply in a wall plug-ready box, featuring a standby/laser ON switch and remote-control options via analog, RS-232, and USB interface. It enables and simplifies stand-alone applications.

What’s more, laser parameters stay stable over time due to Coherent’s unique and patented Permalign technology: the optical components are aligned to optimum and then soldered. Therewith the optimal alignment is frozen over the lifetime of the product, the laser becomes highly insensitive to vibration and thermal cycles. All Sapphire lasers are manufactured in controlled cleanrooms and hermetically sealed, before being run through rigorous testing procedures designed to keep variances from laser to laser to a minimum. This results into lasers with outstanding performance characteristics, best unit-to-unit consistency, and superior lifetimes.

Sapphire provides wavelengths formerly available only with ion and Nd:YAG/ YVO4 lasers but avoids disadvantages of these technologies. Due to the compatibility with their legacy wavelengths instrument manufacturers can directly integrate Sapphire into their existing designs and use the same optics and filters as already employed.

The new Sapphire SF NX lasers provides single-frequency operation with an ultra-narrow linewidth of < 1.5 MHz at 488 nm and 532 nm for applications such as Raman spectroscopy, flow cytometry, holography, and metrology.

Sapphire comes with a flexible interface concept: analog, RS-232 or USB – it is up you to select your communication channel. This interface concept has been designed to support your laser application and sustain the fast changing demands and developments of your industry in the coming years. The modular concept with small-footprint components and high electrical efficiency further facilitates and simplifies integration not only into OEM instrumentation with their reduced physical, electrical and thermal demands.

Sapphire continuously expand and update the product spectrum with legacy and customized wavelength products to optimally cope with your demand and to enable future applications. Independent of the wavelength, all Sapphire versions come with the same form-fit and function:
