Lasers for biophotonics and machining

Toptica debuted several new lasers and enhancements at SPIE Photonics West.

One of the new lasers is the FFI PicoFYb, a picosecond Ytterbium fiber laser designed for seeding medical and industrial laser systems such as ophthalmology, optical sampling and micro-machining. The FFI Osc lasers are fiber-only systems pumped by telecom laser diodes. The driver electronics is integrated in the compact laser head. The combination of saturable absorber technology and fibers guarantees today's ultimate in robustness and reliability. Further benefits of this most economic ultrafast technology include excellent amplitude and wavelength stability. The fiber-coupled FFI Osc lasers have power levels up to 50 mW.

TOPTICA next unveiled three answers to the white laser revolution: widely tunable visible lasers, visible supercontinuums and infrared supercontinuums. The broadband supercontinuums are generated in photonic crystal fibers (PCF) or highly nonlinear fibers (HNLF). For superior power per nm and highest power stability, TOPTICA has developed the unique narrowband tunable VIS. It is based on frequency doubling the stable and powerful infrared supercontinuum. The total power in the infrared supercontinuum (range 1000 - 2100 nm, configuration FFS.SYS-CONT) is typically 150 mW.

The company also introduced two new modules that serve to control the linewidth of tunable diode lasers. The Fast Analog Linewidth Control module FALC 110 is a high bandwidth regulator for laser linewidth reduction and fast frequency locking. The Laser Coherence Control unit LCC, by contrast, provides a modulation source to broaden the laser linewidth up to GHz ranges, maintaining single-line emission and spectral control.
