altTOPTICA Photonics AG (Graefelfing, Germany) offers the TA 100 single-mode output diode laser and amplifier systems, which may serve as a replacement for dye- or frequency-doubled solidstate lasers. The red-wavelength lasers provide a sensing range of 660 to 673 nm and an output power of 250 mW. The amplifier systems provide a sensing range of 660 to 1,080 nm with power up to 1 Watt. They offer single spatial and spectral mode output, narrow line width, and tenability. They can boost the output power of diode or gas lasers by a factor of 100. Applications include interferometry, holography, Raman spectroscopy, and atom cooling and trapping. The systems also enable accessibility to the resonance line of Lithium at 671 nm.
