The HSL 1 (Dutch: Hogesnelheidslijn 1, English: High-Speed Line 1) is a high-speed rail line which connects Brussels, Belgium, with the LGV Nord at the Belgium–France border. It is 88 km (55 mi) long with 71 km (44 mi) of dedicated high-speed …

比利時1號高速鐵路（法語： Ligne à Grande Vitesse 1 ，簡稱LGV 1；荷蘭語： Hogesnelheidslijn 1 ，簡稱HSL 1；英語： High-Speed Line 1 ）是比利時首條高速鐵路，連接着法國高速鐵路北線支線至比利時布魯塞爾南站，於1997年12月14日通車，時速300公里。總建設費約為14億2000萬 ...

Tunable VCSEL（Vertical Cavity Surface Emitting Laser）HSL-1融合了santec自主研发的MEMS技术和VCSEL技术，是一款单模高速波长扫描光源。 其实现了卓越的量产性、高可靠性、寿命长、低功耗。

HSL-1 is based on advanced electrically pumped VCSEL (vertical cavity surface emitting laser) technology. It delivers the best in class performance including long coherence length, variable scan rate and low signal noise.

HSL 1 connects Brussels with the French border. 88 km (55 mi) long (71 km (44 mi) dedicated high-speed tracks, 17 km (11 mi) modernised lines), it began service on 14 December 1997. The line has appreciably shortened rail journeys, the journey from Paris to Brussels now taking 1:22.

HSL-1型直升机由一台普惠（Pratt&Whitney）R-2800-50型径向发动机提供动力输入，其出轴功率约为2400轴马力，发动机安装在机身后部，然后通过穿越机身的传动轴为前部的旋翼提供输入功率。

HSL-IN-1 (compound 24b) is a potent and orally active hormone sensitive lipase (HSL) inhibitor (IC 50 =2 nM) with a significantly reduced reactive metabolite liability.

The Bell HSL (Model 61) was an American 1950s anti-submarine warfare (ASW) helicopter built by the Bell Helicopter company, the only tandem rotor type designed by Bell. It had its first flight in 1953 and entered service with the U.S. Navy in 1957.

The HSL-1 is based on advanced electrically pumped VCSEL (Vertical Cavity Surface Emitting Laser) technology. An attractive laser for SS-OCT applications the HSL-1 takes advantage of a number of features intrinsic to VCSELs to deliver best-in-class performance, including long coherence length, variable scan speed and low signal noise.

Santec 圣德科 HSL-1 传感激光器. 1060nm的单模高速波长扫描激光器。 通过使用Tunable VCSEL技术，实现了单模式发射的高速波长扫描。因为是用半导体工艺制造，所以量产性很好。扫描速度、频带等可以通过程序可变。也可以通过触发输出与其他机器同步。
