Portable Raman Equipment
Higher-resolution portable systems that go where the sample is.
Process Raman
Fiber-coupled sources for in-line monitoring in demanding plant environments.
Solid State Laser Seeding and Pumping
Wavelength-stabilized seed and pump lasers in place of costly DFB and external-cavity units.
Remote Sensing
Ultra-stable single-frequency power for particle detection and gas sensing.
Difference Frequency Generation and Gas Sensing
Two stabilized wavelengths combined to reach the mid-IR for trace-gas detection.
Metrology and Interferometry
High-precision laser distance measurement, a demanding application for semiconductor lasers.

Narrow-linewidth lasers for optical molasses and trapping atomic ensembles in magneto-optical traps.
Quantum Computing
IPS lasers have been used in quantum computing and other scientific fields.
Specifications
DETAILED INFORMATION
Innovative Photonic Solution’s proprietary Wavelength Stabilized Laser features high output power with narrow spectral bandwidth. The laser’s stabilized peak wavelength remains “locked” regardless of case temperature (15 to 45 deg. C).
Devices can be spectrally tailored to suit application needs and offer side mode suppression ratios (SMSRs) better than 40 dB, thereby providing extremely high signal to noise ratio and making these sources ideal for Raman spectroscopy and pump laser applications. The laser is integrated with high performance laser drive and temperature control electronics in a compact package.
In addition to integration into systems, IPS’ OEM U-Type module is designed to “drop in” to our UL/CE and IEC certified turnkey modules to offer wavelength flexibility at a lower cost.
