Seeded Surelite

Product catalog summary

Overview: The Seeded Surelite High Energy Nd:YAG laser system is designed to produce ultra-narrow single longitudinal mode (SLM) outputs with a smooth temporal profile. This is achieved through an injection seeder system that uses a single mode continuous wave diode-pumped fiber laser.

Key Features:

RS-232 or TTL interface for remote or local operation.
Water to air heat exchanger eliminates the need for external water cooling.
Gaussian optics for low divergence and high spatial uniformity.
Graphite resonator structure for thermal and mechanical stability.

Applications:

Material sorting, weld inspection, cleaning, and LIBS in industrial settings.
Medical applications such as skin surfacing, tattoo removal, and as a pump source for medical device manufacturing.
Scientific applications including LIDAR, Thomson Scattering, Laser Thermal Annealing, and more.

Specifications:

Energy stability and power drift are specified for various wavelengths (1064 nm, 532 nm, 355 nm, 266 nm).
Repetition rate of 10 Hz with energy ranging from 4 to 7 mJ depending on the wavelength.
Pulsewidth and linewidth specifications are provided for both standard and injection seeded modes.
Beam divergence and diameter are specified, with a focus on beam pointing stability.

Physical Layout:

Dimensions for the optical head, power supply, and seeder supply are provided.
Weight details for each component are included.
Electrical service requirements and room temperature operating conditions are specified.

Safety Warning: The document includes a laser safety warning to avoid eye or skin exposure to direct or scattered radiation.

Catalog excerpts

Seeded Surelite" High Energy Nd:YAC The injection seeder system for the Surelite Family produces ultra-narrow single longitudinal mode (SLM) outputs with a smooth temporal profile. Seeding is accomplished by injecting a seed beam from a single mode cw diode pumped fiber laser into the Surelite oscillator. Amplitude pioneered the commercial introduction of this technique and holds the patent on its use with radially variable reflectivity resonator optics*. Important applications that require narrow linewidth include pumping narrow linewidth tunable systems, holography, and Doppler LIDAR. * U.S. Patent # 4,918,704 Applications Industry: > Material sorting (recycling) > Weld inspection > Cleaning > LIBS Science: > LIDAR > Thomson Scattering > Laser Thermal Annealing > Pump Source > LIF, PLIF, LIBS Medical: > Skin Surfacing > Tattoo Removal > Pump Source > Medical device manufacturing Features > RS-232 or TTL interface for remote or local operation > Water to air heat exchanger eliminates the need for external water cooling > Gaussian optics incorporated to provide low divergence and high spatial uniformity in beam > Graphite resonator structure ensures long-term thermal and mechanical stability
