Key Points

An amplification gain of approximately 716 was achieved using a Cr:ZnSe amplifier, demonstrating its effectiveness.
Pulse energies of 4.6 µJ were attained, indicating the potential for high output in ultrashort pulse applications.
The system utilized a 1 kHz Q-switched Er:YAG laser pumped for efficient pulse amplification in the ultrashort regime.
Performance evaluations highlight that Cr:ZnSe gain elements significantly enhance laser pulse energy output.

Implication

Analysis shows a gain of ~716 in ultrashort pulses using a Cr:ZnSe amplifier, highlighting its efficiency.

Abstract

We present a Cr:ZnSe amplifier pumped by a 1 kHz Q-switched Er:YAG laser for single pulses picked at 1 kHz from an 80 MHz Cr:ZnS Kerr-lens mode-locked femtosecond laser. An amplification gain of ~ 716 was achieved with pulse energies of 4.6 µJ.
