Introduction to TiF DP diode pumped DPSS titanium sapphire femtosecond laser

Date: 2023-11-01Read: 0

AVESTA has launched a new TiF DP diode pumped DPSS titanium sapphire femtosecond laser system, in which the medium is directly pumped by the laser diode, eliminating the need for expensive additional independent high-power DPSS continuous lasers as pump sources. This structure can significantly reduce system costs, make the volume more compact and small, while still maintaining the output beam quality, pulse width, and long-term power stability of traditional DPSS laser pumped femtosecond laser systems. The TiF DP system supports a wavelength range of 760-840 nm and an average output power of up to 200 mW. It can be used as a seed laser source for amplifier systems and in many other scientific research applications. The laser is designed with a sturdy single-chip thermally stable body, ensuring long-term output power stability below 0.5% rms.

Product Features:

-Integrated diode pump source with control unit
