The invention of optical frequency combs (OFCs) based on femtosecond (fs) mode-locked
lasers has merged laser based spectroscopy with fs-laser technology. OFCs have triggered …

Ti: sapphire laser has an important position in ultrashort pulse generation and wavelength
tuning. The use of expensive frequency‐doubled diode‐pumped solid‐state laser as the …

Single-cycle optical pulses with controllable carrier-envelope phase (CEP) form the basis to
manipulate the nonlinear polarization of matter on a sub-femtosecond time scale. Moreover …

Lasers based on Cr^ 2+-doped II-VI material, often known as the Ti: Sapphire of the mid-
infrared, can directly provide few-cycle pulses with octave-spanning spectra, and serve as …

Abstract Cr: Colquiriite laser materials (Cr: LiCAF, Cr: LiSAF, Cr: LiSGaF) own broad
absorption bands in the visible region that allow direct-diode pum** by well-developed …

This work is to investigate the subsurface damage distribution law and suppression methods
in sapphire ultra-precision grinding. The grinding strategies of rough grinding, semi-finish …

So far, the operation of ultrafast bulk laser oscillators based on Yb-doped gain materials and
directly emitting few-cycle pulses have been restricted to low optical-to-optical efficiencies …

Diode-pumped Cr: ZnS oscillators have emerged as precursors for single-cycle infrared
pulse generation with excellent noise performance. Here we demonstrate a Cr: ZnS …

We investigate terahertz time-domain spectroscopy using a low-noise dual-frequency-comb
laser based on a single spatially multiplexed laser cavity. The laser cavity includes a …

In this article we present a directly diode-pumped high-power Kerr-lens mode-locked Yb:
CALGO bulk laser oscillator operating at 1-GHz repetition rate. We report on two laser …
