The New Focus VAMP™ series of Tapered Amplifiers are designed to provide up to 2 W of amplified power at a variety of infrared wavelengths. The VAMP will faithfully amplify tunable single-frequency light produced by External Cavity Diode Lasers as well as other light sources of appropriate wavelength.
The New Focus engineering team designed reliability and ease of use into the VAMP as well as performance. Fiber-coupling input ensures fast, easy, and reliable alignment. Simply make a secure connection with your FC/APC fiber and that's it - no tweaking. Active input power monitoring insures that self lasing won't damage the tapered amplifier chip. A power lock loop monitors and levels the output power to provide quiet, low-drift output all day long even when your laboratory environment changes. A simple USB driven GUI provides all the control you need.
When seeded with a low-ASE source such as the Vortex™ II or Velocity™ lasers the VAMP faithfully reproduces the narrow linewidth and high contrast ratio. The VAMP will also accept other seed sources, including many home-made ECDLs. Contact our tech support for help in seeding the VAMP.
If you don't see the wavelength you need, speak to your regional sales manager. We are always expanding our capabilities.

1. The TA-7600 series of Tapered Amplifiers is available at many wavelengths. If you do not see your target wavelength, please contact your regional sales manager or representative for further information.
2. At Center Wavelength. Contact factory for power at your specific wavelength. Specifications (other than output power) are when seeded by a New Focus Vortex II or Velocity laser. Minimum fiber-coupled seed power is required to reach specified output power. All specifications subject to change without notice.
3.Minimum seed power is 30 mW for TA-7608 (300 mW output power is achieved with a 9 mW Vortex II seed laser), 15 mW for TA-7612, TA-7616, TA-7614, 20 mW for TA-7613, TA-7613-H and 10 mW for TA-7618 to achieve full specified power output. The tapered amplifier has a safety shutoff feature, activated below 5 mW, that prevents damage to the tapered chip.
