Applications
Raman Microscopy
Sources for Raman microscopes, where the spot is focused to very small dimensions.
Raman Spectroscopy
Excitation sources behind more than 70% of Raman system integrators.
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.
Atomic Clocks
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
Our Digital L-Type provides the user with a powerful and extremely stable laser source that is ideal for numerous scientific applications.
Our 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 power and temperature are “locked” to avoid mode-hops.
