Higher Resolution

Higher Resolution

Resolution is important in any laser-based spectroscopy, whether it’s time resolution, frequency resolution, or mass resolution. The laser is a key component that can determine what resolution a spectrometer or home-built spectroscopy setup can achieve. But it also represents a significant cost component. That means you need a high-reliability laser that delivers exactly the performance you need to match your application. Coherent has many decades of experience supporting all types of laser spectroscopy. We can guide you to the perfect match that meets your needs and your budget.

The Power of Raman Spectroscopy

Amplify: Raman Spectroscopy

Success Story

University of California, San Diego

“To obtain a full set of spectra at different delay times – 3DSFG data – we sometimes have to average data for 48 hours, which puts extreme demands on laser stability. During this period it is critical that the amplifier output be stable and without drifts in beam pointing, beam quality, pulse energy, etc.”

— Professor Wei Ziong, University of California, San Diego
