The CPA-2161 is the fifth in a series of chirped-pulse amplified Ti:Sapphire laser system - representing yet another step forward in this popular technology.
The turnkey, NO TWEAK™ design of this extremely compact laser system further accentuates its productivity and usability. Ingenious technology and engineering is key to this systems compactness and reliability. The only fully-integrated (non-breadboard) system on the market today, the CPA-2161 comprises a diode-pumped seed laser (mode-locked fiber laser), pulse stretcher, Ti:Sapphire regenerative amplifier, pulse compressor and Nd:YAG kHz pump laser head in one compact, all-in-one-box housing. The CPA-2161 includes user-adjustable repetition rate from 3 kHz to 6 kHz and is fully compatible with our NOPA® optical parametric amplifier. Particular attention has been given to optimize spatial mode quality for use in micromachining.
