The novel TiF-DP system is a Ti:Sapphire femtosecond laser oscillator having its active medium directly pumped by emission from a laser diode assembly. Such architecture leads to significant cost reduction while system still maintains the output beam quality, pulse duration and long-term output power stability of conventional DPSS-laser-pumped systems. Average output power reaches 200 mW and is sufficient enough to use the TiF-DP series systems as a seed laser source for amplifier systems with enough headroom, as well as implement it in numerous scientific research applications. The laser design features a rigid monolithic thermally stabilized body and ensures long-term output power stability drift below 0.5% rms.
The laser system may be factory-optimized for any of the three main output pulse duration choices: 20, 30 or 50 fs (with 100 fs by special request). The general rule is that accessible values of output power and tuning range width increase with values of output pulse duration.
- measurement of spectrum shape and FWHM data in the laser's software with real-time pulse duration tuning via PC (in certain models);
- measurement and real-time tuning of central output wavelength via PC;
- oscillator regime indicator (CW regime or pulsed regime with mode-locking) on a PC or with an LED on the laser's body;
- remote mode-lock start or automatic start via PC;
- stabilization of output average power of the laser system;
- analog sync electric output for pulse train monitoring and third-party equipment synchronization.
- oscillator regime indicator (CW regime or pulsed regime with mode-locking) with an LED on the laser's body;
- remote mode-lock start via external wired push-button;
- analog sync electric output for pulse train monitoring and third-party equipment synchronization.
