The New Focus™ VAMP series Tapered Amplifiers is your solution for high-power tunable and fixed-wavelength applications such as atomic cooling, spectroscopy, and Bose-Einstein Condensation. The VAMP will faithfully amplify tunable single-frequency light produced by External Cavity Diode Lasers as well as other light sources of appropriate wavelength. All New Focus tapered amplifiers include an isolator on the output as standard.
Applications
- Quantum Physics
- Laser cooling
- Magneto-optic trapping (MOT)

Footnotes:
- Due to our continuous product improvement program, specifications are subject to change without notice.
- Contact us for all available wavelengths.
- Power at center wavelength when seeded with appropriate wavelength and power. Contact us for output power at specific seed wavelength and for all available output powers.
- Integrated 35 dB optical isolaton. Fiber-coupled option includes isolator and permanently fixed Panda type PM fiber with FC/APC connector for laser output. Wide-type alignment key aligned with the slow axis of the PM fiber. Dual stage isolation, other fiber types and connectors available upon request. Fiber-coupled output option unavailable for TA-7613-H and TA-7618.
- Minimum seed power is 15 mW for TA-7612, TA-7616, 20 mW for TA-7613, TA-7613-H, TA-7614-H and 10 mW for TA-7618 to achieve full specified power output. Safety shutoff activated below 10 mW input power. Fiber-coupled input only. Fiber-coupled configuration of the New Focus Vortex Plus, Velocity, and SWL is compatible to the tapered amplifier input. 70 dB isolation recommended between the seed laser and TA-7613-H and TA-7614-H.
Features
Fiber Coupled Input
The VAMP is configured with a fiber coupled input, ensuring fast, easy and reliable alignment. Active input power monitoring triggers a safety shutoff when the seed power drops below 10 mW, preventing self-lasing and protecting the lifetime of the tapered amplifier chip.
Intuitive Control
Simple intuitive control with the TA-7600-LN controller means you are up and running immediately. The TA-7600-LN controller comes standard with tapered amplifier head recognition to automatically set the temperature and current upper limit. It also features front panel control, RS-232 and USB interfaces, and an intuitive GUI.
Compatible Power Sensors
To verify and analyze the output power of your VAMP laser, we recommend the Ophir 3A (7Z02621) thermal power sensor and Centauri laser power meter. Additional information on this laser measurement equipment can be found on the ophiropt.com website. Other Ophir sensors and meters may also be suitable for the VAMP, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
