Thulium Holmium co-doped tunable fiber laser [PDF]

EPJ Web of Conferences
We report a Tm-Ho co-doped fiber laser with continuous tunability between 1965-2120 nm thanks to a rotating diffraction grating in the laser cavity. It delivers an OSNR of over 60 dB at the central wavelength 2060 nm.

Laser Operation of Tm: LuAG Single-Crystal Fiber Grown by the Micro-Pulling down Method

Crystals, 2021
Single crystals fiber (SCF) of LuAG doped with 2.0 at.% thulium has been grown by using micro-pulling down (µ-PD) technique. A continuous-wave output power of 2.44 W was achieved with a slope efficiency of 11.7% using a 783-nm diode laser as pump source.

Widely Tunable Watt-Level Single-Frequency Tm-Doped Fiber Ring Laser as Pump for Mid-IR Frequency Generation

IEEE Photonics Journal, 2016
We demonstrate a thulium-doped fiber ring laser (TDFRL) integrated with an amplifier, which has a watt-level single-frequency output at 2 $\mu\text{m}$ with a 120-nm wavelength tunability. The TDFRL is constructed based on a hybrid ring-linear resonator

CRISPR and Gene Augmentation Rescue Trabecular Meshwork Dysfunction in iPSC Models of Lowe Syndrome

Advanced Science, EarlyView.
By modeling Lowe syndrome using patient‐derived iPSCs, this study establishes a human disease model that faithfully recapitulates OCRL deficiency‐associated ciliary and cytoskeletal defects. The model enables evaluation of both mutation‐agnostic DNA augmentation and CRISPR‐mediated mutation correction strategies, both of which restore OCRL function and

Temperature investigation of low SWaP thulium-doped fiber lasers

Optics Express
We investigate the temperature dependence of an in-band core-pumped thulium-doped fiber laser with a low SWaP (size, weight, and power) architecture. The temperature investigation is carried out both experimentally and numerically by a simulation model.
