Let RPMC help you find the right laser today!

Single-frequency lasers and ultrafast fiber lasers for Raman Spectroscopy:

• identify molecules using their chemical fingerprint
• study vibrational, rotational and other low-frequency modes
• based on inelastic (Raman) scattering of monochromatic light
• requires low-noise single-frequency lasers or ultrafast fiber lasers

Most recently, upcoming time-resolved Raman spectroscopy and microscopy application (i.e., measurements on airplane engine exhausts to optimize the combustion process and reduce fuel consumption) trigger the need for pulsed laser sources operating in the femto- and picosecond regime. This demand is covered by the FemtoFiber laser family, which have already proven its outstanding performance and suitability in various broadband CARS and SRS applications.

MatchBox single longitudinal mode lasers are a perfect choice for Raman applications due to their convenience in integration into spectroscopy and microscopy systems. This laser was designed with a focus on compactness and performance. Its remarkable stability, narrow linewidth, and high beam quality make it an ideal choice for demanding Raman spectroscopy applications. Small footprint, units with fibers and exceptional performance empower researchers to conduct precise molecular analysis with ease, providing a reliable source for studying molecular vibrational modes and achieving outstanding spectral results. Most often used wavelengths are: 405 nm, 488 nm, 532 nm, 633 nm, 785 nm, 830 nm, 1030 nm, 1064 nm. Integrated Optics supplies CW single-longitudinal mode lasers with all the mentioned wavelengths for a competitive price and possible free-space configuration with clean-up filter integrated inside the laser housing.

Cobolt lasers offer the world’s broadest range of compact lasers perfectly suited for high resolution Raman spectroscopy applications. The stable single-frequency operation, combined with the ultra-robust thermo-mechanical architecture of HTCure , provides narrow linewidths (<1 MHz for all DPLs) over a large range of operating temperatures. It comes with an extremely low spectral drift (<1 pm) and a spectral purity guaranteed to be better than 80 dB (typically much better). This allows for a very high-resolution Raman spectroscopy and a possibility to detect low frequency Raman signals even down in the THz regime.

Here are specific Cobolt lasers for Raman:

• The Cobolt 04-01 Series lasers are continuous-wave diode-pumped lasers (DPL) operating at a fixed wavelength between 457 nm and 1064 nm. Single frequency operation provides an ultra-narrow spectral linewidth, long coherence length and excellent spectral purity. The lasers are designed and manufactured to ensure a high level of reliability.
• The Cobolt 05-01 Series lasers are continuous-wave diode pumped lasers (DPL) operating at a fixed wavelength between 320 nm and 1064 nm. The single frequency operation provides an ultra-narrow spectral linewidth, long coherence length and excellent spectral purity. All control electronics are contained in the laser head eliminating the need for an external controller and bringing the trusted laser performance of Cobolt 05-01 Series into a compact, self-contained device.
• The Cobolt 08-01 Series is a family of compact narrow linewidth continuous-wave lasers, including high performance single frequency diode pumped lasers (DPL) as well as frequency stabilized diode lasers (NLD). This Series offers the broadest wavelength range and highest performance lasers on the market for Raman spectroscopy.
