eMRO™ - M01 Series Single-Frequency Lasers ·1064 & 1319 nm
Single-frequency, ultra-stable lasers built on the proven NPRO design — engineered for precision optics, photonics and metrology laboratories where frequency stability is the specification that matters.

OVERVIEW
Superior performance and long-term value for a laser and optics laboratory
The eMRO™ is based on NPRO™ technology, with proven frequency stability and single mode operation. Its modular design and small footprint reduce space requirements on an optics table, and the eMRO™-M01 series is available in several power and wavelength configurations.
Designed for precision laser, optics and metrology laboratories, the eMRO™ delivers exceptional performance and long-term reliability. The modular pump design allows for indefinite extension of the laser head's lifespan — so the investment holds its value across years of continuous laboratory service rather than being consumed by a single pump-diode end-of-life.
SN&N Electronics has designed and manufactured lasers, optical trains and optoelectronic subsystems for over 30 years — including frequency standards and instruments flown in space-qualified programs.
KEY FEATURES
What sets the eMRO™ apart
Modular design
Separate laser diode and crystal units.
Field-replaceable pump
Send the pump module back for service or a power upgrade without disturbing the laser head. The head outlives the diode that drives it.
Ultra stable
Single frequency, single transverse mode with low frequency drift.
Low noise
All analog laser diode drivers and temperature controllers enable very quiet laser operation.
Low RIN
Custom noise eater feedback circuit suppresses YAG relaxation oscillations.
Frequency selections
1064 nm and 1319 nm.
Frequency agility
Fast (PZT) and slow (temperature) actuators enable frequency tuning.
Easy user interface
Controlled through PC or Android application.

APPLICATIONS
Where the eMRO™ is used
Gravitational wave detectors
Space-based interferometers need a seed laser whose frequency noise stays below the strain they are trying to measure — SN&N built the laser drive electronics for the NASA/ESA LISA program.
Precision metrology
Optical clocks and frequency standards resolve parts in 1015 or better — our electronics drive the Stanford NICE-OHMS optical clock, documented in Portfolio and in a peer-reviewed paper.
Amplifier seed source
A narrow, quiet seed for fiber and solid-state amplifier chains scaling to high power.
Injection seeding
Locks a pulsed or Q-switched oscillator to a single longitudinal mode, shot to shot.
Interferometry
Coherence length measured in kilometres, so path imbalance stops limiting the measurement.
Coherent detection
A local oscillator clean enough to recover phase, not just amplitude, at the receiver.
LIDAR
FMCW and Doppler ranging, where linewidth sets both velocity and range resolution.
Satellite communication
Free-space optical links that hold lock across thermal and vibration extremes.
RF generation via beat notes
Heterodyne two units to synthesise low-phase-noise microwave tones optically.
Fiber-optic gyros
Rotation sensing for navigation, where bias stability follows source stability.
Quantum & atomic physics
Trapping, cooling and Raman beams that demand a stable, lockable single frequency.
Distributed fiber sensing
Phase-sensitive OTDR for pipeline, perimeter and structural monitoring over long spans.
BEHIND THE PRODUCT
SN&N Electronics was founded in 1994 by Dr. Shally Saraf, an expert in electrical and optical engineering with a Ph.D. from Stanford University, more than 30 years in design engineering and project management, and over 100 published papers. He has taught electrical engineering, optics, laser technology and quantum electronics at multiple universities and remains actively engaged in experimental physics research at Stanford.
Alongside the eMRO™ line, SN&N designs and manufactures solid-state, fiber and semiconductor lasers, optical trains, optoelectronic subsystems, frequency standards and microscopes for single-molecule detection — all supported by an in-house production line.
